Question

In the figure above, circles A and B are tangent to each other and to the large circle. If the radius of circle A

in 6 and the radius of circle B is 2, what is the area of the large circle?

Answer 1

The answer to your question is A = 200.96 u²

Explanation:

Data

Radius A = 6

Radius B = 2

π = 3.14

Area = ?

Formula

Area = πr²

Process

1.- Calculate the radius of the large circle

Radius = radius of circle A + radius of circle B

Radius = 6 + 2

Radius = 8

2.- Substitute in the formula

Area = (3.14)(8)²

Area = 3.14(64)

Area = 200.96 u²
