A certain bakery sells two sizes of round cakes. The radius of the large cake is 3 times the radius of the small cake. If the top of the large cake has an area of 261 in?, what is the area of the top of the small cake?​

Answers

Answer 1
Let R be the radius of the large cake.
R x R x π = 261
R² = 83.078
R = 9.11

Small cake radius = 9.11/3
small cake radius = 3.038

Area of small cake = 3.038 x 3.038 x π
Area of small cake = 29 in²

Can i have brainliest?

Answer:

528 Cubic Inches

Step-by-step explanation:

The first thing you would do is, since the equation states that the total height of the bench is 8 inches, is place 4 as the height of the rectangular prism piece of the bench. Next you would use of the dimensions of each of pieces of the bench to calculate the area of each piece respectively using the equation l*w*h. The equations are 4*4*25 which equals 400, 4*4*4 which equals 64, and 4*4*4 which equals 64. Next, you would add them all together which gives you a grand total of 528 cubic inches.

How do you solve this equation

-2x-7y=6

Answers

Answer: x=4, y=-2

For this system of equations, we can use the elimination method, where two variables from both equations will cancel our (in this case, 2x and -2x.

Adding the equations gives us -2y=4, where solving for y gives us -2.

Plugging -2 into any of the two equations and solving for x will result in x=4.

Three vertices of parallelogram WZXY are W(-5, 2), X(2, 4) and Z(-7, -3). Find the coordinated of the vertex, Y.

Answers

Answer:

[tex]Y = (4,9)[/tex]

Step-by-step explanation:

Given

[tex]W(x_1,y_1) = (-5, 2)[/tex]

[tex]Z(x_4,y_4) = (-7, -3)[/tex]

[tex]X(x_2,y_2) = (2, 4)[/tex]

Required

Find Y

To do this, we make use of the mid-point formula

i.e.

[tex]M = \frac{1}{2}(x_n+x_m,y_n+y_m})[/tex]

WX and ZY are the diagonals of the parallelogram.

The mid-point of WX is:

[tex]M = \frac{1}{2}(-5+2,2+4)[/tex]

[tex]M = \frac{1}{2}(-3,6)[/tex]

The mid-point of ZY is:

[tex]M = \frac{1}{2}(-7+x,-3+y)[/tex]

Equate both values of M

[tex]\frac{1}{2}(-3,6) = \frac{1}{2}(-7+x,-3+y)[/tex]

Multiply both sides by 2

[tex](-3,6) = (-7+x,-3+y)[/tex]

By comparison:

[tex]-7 + x = -3[/tex]

[tex]-3 + y = 6[/tex]

[tex]-7 + x = -3[/tex]

[tex]x = 7 -3[/tex]

[tex]x = 4[/tex]

[tex]-3 + y = 6[/tex]

[tex]y = 6 +3[/tex]

[tex]y = 9[/tex]

Hence:

[tex]Y = (4,9)[/tex]

What is 11/2 subtracted by 11/3​

Answers

Answer:

11/6

Step-by-step explanation:

Answer:

1 5/6

First make it a mixed number. 11/2=5 1/2. 11/3=3 2/3. Next, you find the common denominator. 2 and 3 are both multiples of 6. You multiply 11x3=33, 2x3=6, 11x2=22 3x2= 6. Your new numbers are 5 3/6 and 3 4/6. Now you subtract. 5-3=2, but you have to regroup, so you end up with 1. 9/6-4/6=5/6. 1+5/6=1 5/6
