Q:
# The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the total area of the composite figure rounded to the nearest hundredth?

Accepted Solution

A:

Answer:13.35 millimeter. (About)Step-by-step explanation:To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a semicircle, you use the the formula:πr²/2So, if the radius is 8.5, 8.5 · 3.14 = 26.69Now we divide it by 2.26.69 = 13.345Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
