What is the best approximation for the area of this figure?
Use 3.14 to approximate pi.

A. 15.5

B. 16.7

C. 26.1

D. 40.3

Answer 1

area of whole fig.= area of rectangle + area of semicircle
area of rectangle= l x b
= 6x2
= 12
area of semicircle= 1/2πr2
=1/2x3.14x3/2x3/2
=3.53
area of fig = 12+3.53
=15.5
and is (a)
