What is the diameter of the cylinder if the height is 13, and the volume is 1256? Use 3.14 for pi.

Sergio039 [100]

Volume of a cylinder = πr²h

1256 = (3.14) x (r)² x (13)

1256 = 40.82r²

r² = 1256 ÷ 40.82

r² = 30.769

r = √30.69

r = 5.547

Diameter = Radius x 2

Diameter = 5.547 x 2

Diameter = 11.09 units (nearest hundredth)

The Hudson high school wrestling team just won the state tournament and have been awarded a triangular pennant to hang on the wa

Eduardwww [97]

Answer:

3 feet.

Step-by-step explanation:

Base of the triangular pennant = 1.5 feet long.
Area of the triangular pennant = 2.25 Square feet.

Now, we know that:

Area of a Triangle $=\frac{1}{2}$ X Base X Height$

Substituting the given values, we have:

$2.25=\dfrac{1}{2}$ X 1.5 X Height\\\\2.25=$\dfrac{1.5}{2}$ X Height\\\\Cross multiply\\\\2.25*2=1.5 X Height\\\\Divide both sides by 1.5 to solve for the height\\\\\dfrac{2.25*2}{1.5}=\dfrac{1.5 X Height}{1.5}\\\\$Height of the Triangle =3 feet$
