The radius of a circle is 7 inches. What is the circle's area?
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle and π is a constant equal to approximately 3.14.
Substituting r = 7 into the formula, we get:
A = π(7)^2
A = π(49)
A ≈ 153.94 square inches
Therefore, the circle's area is approximately 153.94 square inches.
