Question

what is the area of a drumhead with a diameter of 14

Answer 1

Given

d: diameter

d = 14

r = radius

r = 7

Procedure

Drumhead is a circle

In geometry, the area enclosed by a circle of radius r is πr2.

$\begin{gathered} A=\pi\cdot r^2 \\ A=\pi\cdot7^2 \\ A=153.93\text{ } \end{gathered}$

The answer would be 153.93 sq units
