Question

Find the area of each figure and round to the nearest tenth if necessary

Answer 1

Answer:

95.9 cm^2

Step-by-step explanation:

this figure is composed of two semicircles. the area of each semicircle would be determined and then added together.

area of a semicircle = 1/2 nr^2

r = radius

n = 22/7

bigger semicircle

1/2 x (22/7) x (6^2) = 56.57cm^2

smaller circle = 1/2 x (22/7) x (5^2) =39.29cm^2

Sum of the areas = 56.6 + 39.3 = 95.9 cm^2

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
