Find the volume of a cylinder with height 14.7 cm and diameter 10.5 cm.

velikii [3]

Hello!

The volume of a cylinder is found by using the formula: V = πr²h.

The problem has given us the height of the cylinder, which is 14.7 centimeters, and the diameter which is 10.5 centimeters. The volume of a cylinder requires the radius, so therefore, to find the radius, divide the diameter by half, and that will give the radius.

R = 10.5 / 2

R = 5.25 centimeters

With that radius and the height, we can find the volume of the cylinder.

V = π(5.25)²(14.7)

V = 27.5625(14.7)π

V = 405.17π, 1272.23 (multiplied by 3.14), 1272.88 (multiplied by π)

Therefore, the volume of this cylinder is 1272.88 centimeters³.

The function is expressed by a formula y=0.1x+5. Find the value of the function if the variable is equal to 10; 50; 120.

Aleksandr [31]

Answer:

f(x) = 10: $\large\boxed{6}$

f(x) = 50: $\large\boxed{10}$

f(x) = 120: $\large\boxed{17}$

Step-by-step explanation:

Write out the whole function using given information

f(x) = [10, 50, or 120]

Domain/y = 0.1x + 5

Substitute the possible values for x into the domain equation and solve

f(x) = 10: 0.1(10) + 5 = 1 + 5 = 6

f(x) = 50: 0.1(50) + 5 = 5 + 5 = 10

f(x) = 120: 0.1(120) + 5 = 12 + 5 = 17

Final answers:

f(x) = 10: $\large\boxed{6}$

f(x) = 50: $\large\boxed{10}$

f(x) = 120: $\large\boxed{17}$

Hope this helps :)

A punch recipe requires 4/5 of a cup of pineapple juice for every 2 1/2 cups of soda what is the unit rate of soda to pineapple

Cloud [144]

Answer:

Step-by-step explanation:

The unit rate of soda to juice is found by setting up a ratio with soda on top and juice on bottom:

$\frac{2.5}{.8}$

If you divide this out, you will get 25/8 which is 3.125 cups of soda per cup of juice.
