# How do you find the circumference and area of a circle with radius of 7 feet?

Mar 18, 2018

The formula for area is $\pi \times {r}^{2}$ and the circumference is $2 \times \pi \times r$

So if $r = 7$, let's find these values:

$\cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot$

Area

$\pi \times {7}^{2}$

$\pi \times 49$

$49 \pi$ feet

$\cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot$
Circumference

$2 \times \pi \times 7$

$14 \pi$ feet
