Q:
# The circumference of a grapefruit is 4π cm. Find the surface area of the grapefruit. Express your answer in terms of π.a) 16 pie cm2b) 32 pie cm2c) 64 pie cm2d) 72 pie cm2

Accepted Solution

A:

We find radius first:

C = 2 * pie * r

r = C/(2 pie) = 4 pie cm / (2 pie) = 2 cm

Now we find surface area: A = 4r˛ = 4 (2)^2 = 16 pie cm2

Hence the surface area of the grapefruit fruit is 16 pie cm2.

C = 2 * pie * r

r = C/(2 pie) = 4 pie cm / (2 pie) = 2 cm

Now we find surface area: A = 4r˛ = 4 (2)^2 = 16 pie cm2

Hence the surface area of the grapefruit fruit is 16 pie cm2.
