Answer:
The area is 88.39 cm
Step-by-step explanation:
Here, we want to find the area of the semicircle given that the diameter of the semi circle is 15 cm
We start by getting the radius
Mathematically r = D/2
= 15/2 = 7.5
Area of semicircle is area of circle/2
= (pi * r^2)/2
= (22/7 * 7.5^2)/2 = 88.39 cm
You could add the whole number parts first then add the fractions. Finally add the 2 results.
The sum of that is the answer = 3
6/8 = 0.75
0.75 x 100 = 75%
<u>Answer:</u>
(B) $152.50
<u>Step-by-step explanation:</u>
Friday: 5 hours x $7.50 per hour = $37.50
Saturday: 6 hours x $7.50 per hour = $45
Sunday: 4 hours x $7.50 per hour = $30
$40 + $37.50 + $45 + $30 = $152.50
I would have <u>(B) $152.50</u> in total.
