Acircular pool with a 10 foot diameter is surrounded by a deck. what is the area of the deck which surrounds the pool? use 3.14

146.5 sq. feet.

Step-by-step explanation:

Area of the deck = Large Square (with 15 ft side) - Circular Pool (with radius 10/2=5)

Large Square area =

Circular Pool area =

Thus, area of deck surrounding pool = sq. feet

ANSWER

EXPLANATION

The circular pool has diameter,

This means the radius is;

The area of the pool is

The area of the deck is equal to the area of the square minus area of circular pool.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
