Answer 1

Answer:

Step-by-step explanation:

Answer: 1846.32 cubic feet

Work Shown:

V = pi*r^2*h is the volume of any cylinder with radius r, height h

r = 7, h = 12

Plugging those values in gets us this

V = pi*7^2*12

V = pi*49*12

V = pi*588

V = 588*pi

We will use 3.14 for pi, so we replace pi with

this value

V = 588*3.14

V = 1846.32

The units for the volume are in cubic feet. We can abbreviate this to

Answer 2

Answer:

Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of 1: √3 : 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).
