Answer:
The surface area of this cylinder is 3545[tex]\frac{1}{7}[/tex] cm²
Step-by-step explanation:
The formula of the surface area of the cylinder is
Surface area = later area + 2 base area, whereLateral area = perimeter of the base × height of the cylinderLet us use the rules above to solve the question
∵ The base of the cylinder is a circle
∵ The perimeter of the circle = 2 π r
∵ The radius of the cylinder is 12 cm
∴ r = 12
∴ The perimeter of the base = 2 (12) (π)
∴ The perimeter of the base = 24π cm
∵ The height of the cylinder is 35 cm
∴ h = 35 cm
→ By using the rule of the lateral area above
∵ The lateral area = 24π × 35
∵ π = [tex]\frac{22}{7}[/tex]
∴ The lateral area = 24 × [tex]\frac{22}{7}[/tex] × 35
∴ The lateral area = 2640 cm²
∵ The area of the circle = π r²
∴ The area of the base = [tex]\frac{22}{7}[/tex] × (12)² = [tex]\frac{22}{7}[/tex] (144) = 452[tex]\frac{4}{7}[/tex] cm²
→ By using the rule of the surface area above
∴ The surface area = 2640 + 2(452[tex]\frac{4}{7}[/tex]) = 3545[tex]\frac{1}{7}[/tex] cm²
∴ The surface area of this cylinder is 3545[tex]\frac{1}{7}[/tex] cm²

A door 2m*1m is fixed on a wall.The wall is 8.5 long and 2m high.Find the cost of whitewashing the wall ₹40 per square meter
Answer: The cost is $600
Step-by-step explanation: The wall is a rectangle whose area is calculated as:
S = 8.5 x 2
S = 17
However, there is a door on the wall which won't be whitewashed so:
Area of door:
[tex]S_{d}[/tex] = 2 x 1
[tex]S_{d}[/tex] = 2
Whitewashed area will be
S - [tex]S_{d}[/tex] = 17 - 2
S - [tex]S_{d}[/tex] = 15m²
To whitewash the wall, it costs $40 per each m², so:
Cost = 15*40
Cost = 600
To whitewash the wall, it will cost $600.

Based on a sample of 150 textbooks at the store, you find an average of 70.69 and a standard deviation of 29.6. The point estimate is: Incorrect (to 3 decimals) The 99 % confidence interval (use z*) is:______
Answer:
Step-by-step explanation:
Given that:
The sample size = 150
The sample mean = 70.69
The standard deviation = 29.60
The sample mean is equal to the point estimate of the population = 70.69
At 99% confidence interval level is:
∝ = 1 - 0.99
∝ = 0.01
The critical value:
[tex]Z_{\alpha/2} = Z_{0.01/2} \\ \\ Z_{0.005} = 2.58 \ using \ Z \ tables[/tex]
The Margin of error = [tex]Z_{\alpha/2} \times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]= 2.58 \times \dfrac{29.6}{\sqrt{150}}[/tex]
= 2.58 × 2.4168
≅ 6.235
At 99% confidence interval; the estimate of the population mean lies within the interval:
= [tex]\overline x - E < \mu \ < \overline x + E[/tex]
= 70.69 - 6.235 < μ < 70.69 + 6.235
= 64.455 < μ < 76.925
= (64.455 , 76.925 )

Clarence repairs transmission in a workshop in his backyard . He has already repaired eight transmissions the graph in the figure above shows his repair plan . How many more transmissions will he repair if he works for the next 6 days
Assuming that Clarence repaired the eight transmissions using 2 days, he will likely repair 24 transmissions if he works for the next 6 days.
What is a proportion?A proportion shows the relationship between two or more ratios or quantities.
Data and Calculations:Number of transmissions repaired in 2 days = 8
Number of days to repair more transmissions = 6
Estimated number of transmissions to be repaired = 24 (8/2 x 6)
Question Completion:Since the graph was not showed, it is assumed that Clarence completed repairing the 8 transmissions in 2 days.
Thus, assuming that Clarence repaired the eight transmissions using 2 days, he will likely repair 24 transmissions if he works for the next 6 days.

Joelle wants to place an oversized image which is 30.51 cm wide so that it appears centered on the page. The width of the page is 21.59 cm. In the program, horizontal positions to the right of the leftmost edge of the page are positive. What horizontal position for the left edge of the image should Joelle use to center the image?
-4.46cm
Step-by-step explanation:
The horizontal midpoint of the page is;
The horizontal midpoint of the image is given as;
For the image to be centered, these to midpoints must be on the same point in the axis.
If we take the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795cm. The distance that goes beyond this leftmost edge is computed as;
On the axis, this is on the negative side. Therefore, the horizontal position for the left edge of the image that Joelle should use to center the image is -4.46cm.
