Question

The diameter of Z is 5 in. What is its area in terms of pi? (1 point)
2.5in.2
5in.2
6.25in.2
25in.2

Answer 1

\[A=\pi R ^{2}\] A being the Area and R being the Radius
The radius is just half the diameter, so take the diameter and divide it in half and plug your numbers into the equation
\[A=\pi(2.5^{2})\]
\[A=\pi(6.25)\] remember pi is 3.14
\[A=19.63 \inches ^{2}\]
