Hello,

Answer: interior.

C(-2,3) is the center of the circle
R(6,3)
Let's calculate RC²=(6+2)²+(3-3)²=8²
==>RC=8 and radius= 9
The point R is thus interior of the circle.

The fountain is made up of two semicircles and one quarter circle. Find the perimeter and area of the fountain.

antoniya [11.8K]

Answer:

628ft²

Step-by-step explanation:

From the diagram, we are given the following

diameter of the semicircles

2semi circles = 1 circle

Area of 2semicircles = πd²/4

Area of 2semicircles = 3.14(20)²/4

Area of 2semicircles = 3.14*400/4

Area of 2semicircles = 3.14*100

Area of 2semicircles = 314ft²

Area of the quarter circle = πd²/4 * 1/4

Area of the quarter circle = πd²/16

d = 2r

d = 2*20

d = 40ft

Area of the quarter circle = 3.14(40)²/16

Area of the quarter circle = 3.14*1600/16

Area of the quarter circle = 3.14*100

Area of the quarter circle = 314ft²

Area of the fountain = 314ft²+314ft²

Area of the fountain = 628ft²
