Answer:
725.71 cm
Step-by-step explanation:
Using the attached diagram :
Diameter of inner circle = 26
Radius of inner circle = 26/2 = 13
Radius of entire circle = 13 + 7 = 20
The Area of a circle = πr²
Area of inner circle = π13² = 169π
Area of entire circle = π20² = 400π
Area of shaded portion :
Area of entire circle - Area of inner circle
400π - 169π = 231π = 725.71 cm
Given:
Cost of one pound of apples = $1.98
To find:
The cost of 0.75 pound of apples.
