Write an equation to find the missing side lenght. use ? for the number you do not know

Whitepunk [10]

There isn't enough information; however, let's say you were to find the missing side length of a rectangle. The perimeter is 52 and the two given side lengths are both 16. You would set up an equation to find the missing side lengths:
52 = 16 + 16 + ? + ?
52 = 32 + ? + ?
20 = ? + ?
Since this is a rectangle, the two other sides have to be equal. Therefore, you would divide the number by 2.
10 = ?

What is the height of the cone below? V = 45 in^3 B = 5in^2

Lapatulllka [165]

Answer:

The height of the cone is h = 27

Step-by-step explanation:

Formula:-

Step 1:-

The volume of the cone is $V=\frac{1}{3} (base)(height)$

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

Step 2:-

by using formula, we get solution

$45 = \frac{1}{3} (5)(h)$

cross multiplication, we get

$\frac{45 x 3}{5} =h$

now simplification, the height of the cone is h = 27
