CAN SOMEONE PLEASE CHECK ME

Yes everything is absolutely correct. Hope it helps

Mario's:

8 slices with an area of 14.13

8 * 14.13 = 113.04

So the area of the whole pizza is 113.04

Area of a Circle:

A = pi * r^2

113.04 = 3.14 * r^2

113.04 = 3.14r^2

36 = r^2

r = 6

So the radius is 6, now plug it in the formula for the circumference of a circle:

C = 2 * pi * r

C = 2 * 3.14 * 6

C = 37.68

Tito's:

16 slices with an area of 12.56

16 * 12.56 = 200.96

So the area of the whole pizza is 200.96.

A = pi * r^2

200.96 = 3.14 * r^2

200.96 = 3.14r^2

64 = r^2

r = 8

So the radius is 8, now plug it in the formula for the circumference of a circle.

C = 2 * pi * r

C = 2 * 3.14 * 8

C = 50.24

Peter's:

10 slices with an area of 15.386 each

10 * 15.386 = 153.86

So the total area is 153.86

A = pi * r^2

153.86 = 3.14 * r^2

153.86 = 3.14r^2

49 = r^2

r = 7

So this is the radius, now plug it into the formula for the circumference of a circle:

C = 2 * pi * r

C = 2 * 3.14 * 7

C = 43.96

So Mario's had the smallest circumference, then Peter's, then Tito's.

So your answer is correct.

For the 2nd question:

We can set up a proportion:

30/3 = x/264

Multiply 264 to both sides:

x = 264 * 30/3

x = 7920/3

x = 2640

So your answer was incorrect.
