Taylor is making a cookie cake that has a diameter of 13 in. What is the area of a 4th of the cookie cake ?

A) 36.97 in. sq.
B) 36.25
C) 33.18
D) 38.4

Answer 1

radius = half diameter
area of a circular form = \(\pi r^2\), where 'r' is the radius.
and you need to find 1/4th the area, so, you need \(\frac 1 4 \pi r^2\).

can you find this out?
