Answer:

m ∠ L = 54°

Step-by-step explanation:

the angles of triangle are 2x, 3x & 5x

the sum of angles are 180°

2x+3x+5x = 180

10x = 180

x = 180/10 = 18°

m ∠ L = 3x° = 3(18)° = 54°

m ∠ L = 54°

A right circular cylinder has a height of 19 3/4 ft and a diameter 1 2\5 times its height.

alexira [117]

Answer:

Volume of cylinder is 34833.21 ft³

Step-by-step explanation:

Given : A right circular cylinder having height $19\frac{3}{4}$ ft and diameter $\frac{12}{5}$ times its height.

Given : diameter $\frac{12}{5}$ times its height that is

diameter $\frac{12}{5}$ times $19\frac{3}{4}$ that is

Diameter = $\frac{12}{5} \times \frac{79}{4}$

Diameter = $\frac{237}{5}$ ft

Radius is half of diameter,

Radius = $\frac{1}{2} \times \frac{237}{5}=\frac{237}{10}$ ft

$\text{Volume of Cylinder}=\pi r^2h$

Substitute the values, we get,

$\text{Volume of Cylinder}= \pi (\frac{237}{10})^2 \times \frac{79}{4}$

$\text{Volume of Cylinder}= \times 3.14 \times (23.7)^2 \times 19.75$

$\text{Volume of Cylinder}=34833.21$

Thus, volume of cylinder is 34833.21 ft³
