find the radius of a cylinder with a volume of 150in cubed and a height of 10in​ (PLEASE HELP)

Answers

Answer:

2.186

Step-by-step explanation:

V = pi r*r * h

V = 150 in^3

pi = 3.14

h = 10

r^2 = V / (h * pi)

r^2 = 150 / (`10 * 3.14)

r^2 = 150 / 31.4

r^2 = 4.777

sqrt(r^2) = sqrt(4.777)

r = 2.186

The volume of a cylinder is 121 cubic inches and its height is 4 inches.
a)
What is the radius of the cylinder?
b) What is the surface area of the cylinder? Give your answer in terms of īt.

Answers

Answer:

r=3.10in

SA= 138.22 in square

Step-by-step explanation:

Given data

Volume = 121 in^3

Height= 4 in

a) What is the radius of the cylinder?

 We know that volume

 V=πr^2h

121= 3.14*r^2*4

121= 12.56r^2

121/12.56= r^2

9.63=r^2

r= √9.63

r=3.10in

b) What is the surface area of the cylinder? Give your answer in terms of īt.

The surface area of cylinder is expressed as

SA=2πrh+2πr^2

SA= 2*3.14*3.1*4+ 2*3.14*3.1^2

SA= 77.872+60.3508

- Approximately 6.5 x 10^5 gallons of water flow over a waterfall each second. There are 8.6 x 10^4 seconds in 1 day. » Select the approximate number of gallons of water that flow over the waterfall in 1 day. A 5.59 x 10^10 B 5.59 x 10^9 C 5.59 x 10^20 D 5.59 x 10^19​

Answers

Answer:

The approximate number of gallons of water that flow over the waterfall in 1 day is:

A. 5.59 x 10^10

Step-by-step explanation:

To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:

Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/s * 8.6 x 10^4 s

Now, we must cancel the seconds, then:

Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons

How you can see, once you have multiplied these two values, the answer is the same to the option A.
