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

Plz answer last question and im lost!

harkovskaia [24]

Answer:

$\pi$ radian

Step-by-step explanation:

We know that angle for a full circle is 2 $\pi$

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of angle for a full circle = 1/2 * 2 $\pi$ = $\pi$

Thus, answer is $\pi$ radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as $\pi$ radian.

Answer:

27.4 km

Step-by-step explanation:

vertical line- y

17 km/y= tan 54

y= 17/tan 54= 25.2 km

25.2/x= cos 23

x= 25.2/cos 23= 27.4 km
