Answer:

Step-by-step explanation:
The volume is the space an object occupies. The volume formula for a cylinder is provided and it is:

Where:
The radius is the distance from the center of the circle to the edge, and it is 4 feet. The height is 8 feet. We are told to use 3 for pi.
Substitute the values into the formula.

Solve the exponent.
- (4 ft)²= 4 ft * 4 ft = 16 ft²

Multiply the three numbers together.


The volume of the cylinder is approximately <u>384 cubic feet.</u>
Hey there, Alex!
She would expect 55 of them to be left handed.
Work: 550 / 20 = 27.5
27.5 x 2 = 55

The answer is 3.6 or 3 6/10 or 3 3/5 all equivalent
Supplementary angles add to equal 180 degrees. If two angles are supplements of each other and one of the angles measures 62 degrees, you can set its sum with the unknown angle, x, equal to 180 and solve for the unknown angle x.
Equation:
180 = x + 62
Subtract 62 from both sides:
118 = x
Answer:
The measure of the other angle is 118°.
