Question

The radius of a circle is 9 miles. What is the circle's area?

Answer 1

Answer:

254.34 miles²

Step-by-step explanation:

How do we find the area of a circle?

• The area of a circle can be found using πr², where r = radius. We have the radius as 9 miles, and pi is shortened to 3.14.

Solving

• $3.14*9^2$
• $3.14*81$
• $254.34$

Therefore, the area is 254.34 miles².

Answer 2

Answer:

Formula for area of a circle:

πr^2,

where pi is equal to 22/7 or 3.14

and r is the radius that is being squared

Plug in the actual values to this formula to find the area;

a = πr^2

a = 3.14 x 9^2

a = 3.14 x 81

a = 254.34, your answer is 254.34 square miles.
