Question

what is the correct formula for the area of this circle? 10 a = π + 2(10) a = 10π a = π(5²) a = π + 5

Explanation:

Step1: Find radius from diameter

The diameter is 10, so radius $r = \frac{10}{2} = 5$.

Step2: Apply circle area formula

The area formula for a circle is $A = \pi r^2$. Substitute $r=5$: $A = \pi(5^2)$.

Answer:

C. $A = \pi(5^2)$
