Find the volume of a right circular cone that has a height of 16.8 in and a base with a

alexgriva [62]

Answer:

Volume of right circular cone is 388.43 in³

Step-by-step explanation:

Height of circular cone = 16.8 in

Radius of circular cone = 4.7 in

We need to find Volume of right circular cone

The formula used for calculating volume of a right circular cone is: $Volume=\pi r^2\frac{h}{3}$

Putting values and finding volume

$Volume=\pi r^2\frac{h}{3}\\Volume=3.14\times (4.7)^2 \times \frac{16.8}{3}\\Volume=3.14\times 22.09 \times 5.6\\Volume= 388.43 \:in^3$

So, Volume of right circular cone is 388.43 in³

A rectangular kitchen is 4 meters longer than it is wide. If the area of the kitchen is 192 square feet meters, how many meters

Lunna [17]

Lets x = width
length = x + 4 (4 meters longer than wide)

A = L * W
192 = x ( x +4)
192 = x^2 + 4x
x^2 + 4x - 192 = 0
(x +16)(x-12) = 0
x - 12 = 0, x = 12
x + 16 = 0, x = -16
so width x = 12
length = 12 + 4 = 16 (4 meters longer than wide)

If △ABC is an isosceles triangle where AB¯≅AC¯, m∠A=(2x−20)°, and m∠B=(3x+5)°, then m∠C=__________°.

KengaRu [80]

Refer to the diagram shown below.

Because ΔABC is isosceles and AB = AC, therefore
m∠C = m∠B = (3x + 5)°

The sum of angles in a triangle is 180°, therefore
2(3x + 5) + 2x - 20 = 180
6x + 10 + 2x - 20 = 180
8x - 10 = 180
8x = 190
x = 23.75°

Therefore
m∠C = 3x + 5 = 3(23.75) + 5 = 76.25°

Answer: 76.25°
