2. Find the area of a semicircle with diameter as 14cm. (Round your answer to the nearest whole number)
77 Sq. cm
50 Sq. cm
67 Sq. cm
52 Sq. cm

The circumference (perimeter) of the semicircle =  35.99

m

The area of the semicircle =  

76.96

m 2

Step-by-step explanation:

n circles, perimeter and area are both related to diameter, so if you are given the diameter, you can figure out the perimeter and area.

The problem wants the area of a  

semicircle

, so it's best to figure out the area of a complete circle first, and then divide it in half for the area of the semicircle.

Figuring out the perimeter is a little more complicated.

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
