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

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

The rectangle shown has a perimeter of 66 cm and the given areaIts length is 3 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.

Answers

Answer:

The area of the rectangle is equal to the base times the height. That is, major side by minor side. In many places we will find how the height is called "h" and the base "b."

Step-by-step explanation:

The dimensions of rectangle are width of 5cm and Length of 28 cm.

What is Rectangle?

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees

The perimeter of rectangle is

Perimeter=2(Length+width)

Given that  length is 3 more than five times its width.

L=3+5W

Perimeter=2(3+5w+w)

Perimeter of rectangle is given by 66cm

66=2(6w+3)

Apply distributive property on RHS side

66=12W+6

Subtract 6 from both sides

60=12W

Divide both sides by 12

W=5

L=3+5(5)=25+3=28

Hence the dimensions of rectangle are width of 5cm and Length of 28 cm.

Answer:

  yes, 4

Step-by-step explanation:

We assume your sequence is supposed to be ...

  -7, -3, 1, 5

First differences are ...

  -3 -(-7) = 4

  1 -(-3) = 4

  5 -1 = 4

These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.

Answers

6 would be the answer

According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.

What is square root?

The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number.

Given

[tex]\sqrt{\frac{72}{2} }[/tex]

= [tex]\sqrt{36}[/tex]

= 6

According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]

[tex]\sqrt{\frac{72}{2} }[/tex] = [tex]\frac{\sqrt{72} }{\sqrt{2} }[/tex]

= [tex]\frac{6\sqrt{2} }{\sqrt{2} }[/tex]

= 6

Thus, according to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.
