What is the sum of the areas of circle C and circle D?
7
14
49
98
Solution:
The area of a circle is the space occupied by the circle in a two-dimensional plane.
Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle.
The formula for the area of a circle is A = πr2, where r is the radius of the circle.
Consider the center C and D of two circles contain a radius 7 cm
We know that
Area of a circle A = πr2
A = π (7)2
A = 49π cm2
So the sum of the areas of circle C and circle D = 2 (49π) = 98π cm2.
Therefore, the sum of the areas is 98π cm2.
What is the sum of the areas of circle C and circle D? 7 14 49 98
Summary:
The sum of the areas of circle C and circle D is 98π cm2.
