Question

Hey circular trampoline has an area of 132.2 ft.² what is the radius of the trampoline rounded to the nearest tenth

Answer 1

The radius of trampoline is 6.5 feet

Step-by-step explanation:

Area of circular trampoline = 132.2 ft²

Let,

r be the radius of trampoline.

We know that area of circle = $\pi r^2$

Therefore,

$\pi r^2 = 132.2$

Putting value of $\pi = 3.14$

$3.14r^2=132.2$

Dividing both sides by 3.14

$\frac{3.14r^2}{3.14}=\frac{132.2}{3.14}\\r^2=42.10$

Taking square root on both sides

$\sqrt{r^2}= \sqrt{42.10} \\r=6.48 \ ft$

Rounding to nearest tenth,

Radius of trampoline = 6.5 feet

The radius of trampoline is 6.5 feet
