C. ( 12pi + 4) cm
D. ( 12pi + 16) cm

What is the area of the composite figure A 6pi 4 cm B 6pi 16 cm C 12pi 4 cm D 12pi 16 cm class=

Respuesta :

Answer:

16 + 6pi cm

Step-by-step explanation:

We have a square of length 4 cm

A = s^2 = 4^2 = 16

We have 3 semi circles

with radius 2

A semi circle has an area of

1/2 pi r^2 = 1/2 pi (2)^2 = 1/2 (4pi) = 2pi

There are 3 of them

3 * 2 pi = 6pi

Add the areas together for the square and the semicircles

16 + 6pi

Answer:
(6pi + 4) cm^2

Or just A/ first option
