Question

find the area of a circle with radius of 7

Answer 1

Answer:

-The area of a circle:

$A \approx 153.938$

     or

$A \approx 153.94$ (Rounded to nearest hundredth if needed)

Step-by-step explanation:

-Use the formula to find the area of a circle:

$A = \pi r^2$

-After you have the formula set up, use the radius for the formula:

$A = \pi 7^2$

-Then, you solve the formula:

$A = \pi \times 7^2$

$A = \pi \times 49$

$A = 49\pi \approx 153.938$

-Round up to the nearest hundredth (if needed):

$A \approx 153.94$
