Hey everyone can someone please help me with 5c :)
Lostsunrise [7]

Answer:

A=23512.32

Step-by-step explanation:

The equation for the area of a cylinder is A=2πrh+2πr^2

If we substitute the radius and height, the equation would be A=2π(60)(2.4)+2π(60)^2

π can be shortened to 3.14 so it's A=2(3.14)(60)(2.4)+2(3.14)(60)^2

We're left with 904.32+22608

So the answer is 23512.32

The prediction of a variable can be done if we have the independent variable. Which is the required variable that is used to determine the value of the other variable. The variable to be predicted is dependent on the required variable.

An independent variable can also be referred to as a predictor variable. When its value is known, it can be used to obtain the dependent variable.
