Volume of a Cylinder Formula: $\displaystyle V = \pi r^2h$

V is volume
r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 2 ft

Height h = 7 ft

Step 2: Solve for V

Substitute in variables [Volume of a Cylinder Formula]: $\displaystyle V = \pi (2 \ ft)^2(7 \ ft)$
[Volume] Evaluate exponents: $\displaystyle V = \pi (4 \ ft^2)(7 \ ft)$
[Volume] Multiply: $\displaystyle V = 28 \pi \ ft^3$

A right triangle has a hypotenuse of length 9 inches. If one angle is 35 degrees, find the length of each leg.

Montano1993 [528]

90 + 35 = 125.
180 -125 = 55 degrees.

4.59^2 + 6.55^2 = 8^2
21.1 + 42.9= 64 inches
