Fine the area of a circle with a radius of 7 in. Write the formula, substitute, solve.

Answers

Answer 1

Answer:

Formula: A=(pi)r^2

Substitution: A=3.14(7^2)

A=3.14(49)

Solve: A=153.86 in^2

*I personally like to use the pi sign on my calculator to multiply the radius squared by, but my keyboard did not have a pi sign. Usually, the pi sign is more exact. If you used the pi sign, your answer would be 153.94 inches^2. Hope this helps!
