The answer is <span>B. 196 π mi2
</span>
(1) Find radius r:
The area of the circle is:
A = r²π
A = 49π mi²
49π = r²π
49 = r²
r = √49 = 7 mi
(2) Find the surface area of the sphere.
The surface area of the sphere is:
A = 4πr²
r = 7 mi
A = 4π * 7²
A = 4π * 49
A = 196π mi²
1: ‘8’/3x = 1+ 5/3x
2: ‘8’/3x-5/3x= 1+ 5/3x-‘5/3x’
3: ‘3’/3x=1
4: 1

Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder with radius r and height h is given by:

A cylinder has a height of 12 inches and a radius of 1.5 inches.
This means that 
What is its volume?

It's volume is of 84.78 cubic inches.

let's plug in the value of y :
Answer:
$149.09
Step-by-step explanation:
56.75-14.10=42.65
42.65+41.50=84.15
84.15-11.03=73.12
73.12-7.25=65.87
65.87+83.22=149.09
