Question

Selena was finding the area of a circle with the radius of 7 units. Her work is shown below:

A = πr^2

= 3.14 * 7^2

= 3.14 * 14

= 43.96 units^2



What should Selena do to correct the error that she made?


F. Use 14 for the value of r .


G. Use 3.5 for the value of r .


H. Use 49 instead of 14 for 7^2


I. Use the formula 2πr




(Please show your work if possible!)

Answer 1

H

Explanation:

So when finding the area you need to square the radius. In the problem she only multiplied it by two. so she needs to do 49×3.14.

Hope this helps!
