Question

A circular pan has a diameter of 8 inches.

What is the exact area of the pan?

A.
64π square inches

B.
8π square inches

C.
16π square inches

D.
256π square inches

Answer 1

getting people to supply you answers is not learning.

Answer 2

Area is given by the equation pi*r*r

aND r = DIAMETER/2

You have been given the diameter.
Calculate the area! :D

Answer 3

so its 8?

Answer 4

Not quite.

Diameter = 2* radius



So you have been given the diameter = 8 inches
Thus the radius has to be = 4 inches

Area of circle is given by = pi * radius * radius

pi \(\approx\) 3.14 [Universal value of pi]
radius = 4 inches

So area = 3.14 * 4 * 4 = 16 * 3.14 = 16*pi = 16\(\pi\)
