Question

9. Marianna is making a piñata that has a ball-like shape. The piñata has a surface area of 60 square feet. Use

Answer 1

Answer:

D. 2.19

Step-by-step explanation:

ok so the formula for the surface area of a sphere is 4$\pi$$r^2$

We see that 4$\pi$$r^2$=60.

To find the radius we must isolate r on one side of the equations.

$r^2$=60/4$\pi$

$r^2$ = 4.77464829276

r = $\sqrt{4.77464829276}$

That is approximately equal to 2.19
