A
Using the formulas:
A=πr2
d=2r
Solving for A
A=1
4πd2=1
4·π·62≈28.27433ft²
To answer this question we need to use a basic formula to find the area of a circle which is:
pii*radius*radius
Steps:
1. Find the radius
Divide 6 (diameter) by 2 since 2 radius makes up a diameter, so you would get 3 has the radius.
2. Substitute the values
3.14 * 3*3
Which equals 28.26.
Answer:
Exact area—28.26 ft (squared)
Rounded to the nearest tenth—28.3 ft (squared)

Because y varies inversely as x, therefore

where k = constant.
When x = 6, y = 2.5. Ther efore

Cross multiply.
k = 6 x 2.5 = 15
The equation is

When x = 4, obtain

Answer: a. 3.75
That graph would be non-linear
18. 3 (-5 + 1) = 6 x -3 = -18 false its -14
19. 1/2 x 2 + 1/4 x 12 = 8 false its 4
