a.
To calculate the Area of Large
a.
Answer to Problem 32E
Explanation of Solution
Given Information: Diameter of large circle = 18 m, Diameter of small circle = 9 m
Formula Used:Area of circle =
Calculation:
Diameter = d, Radius = r.
Now, diameter is of 9 m
So,
Put the value of diameter to find the radius.
Hence,
Area of circle =
Put the value of radius to find the area of large circle.
Area of large circle =
Area of large circle =
b.
To calculate the Area of Small Circle.
b.
