Jobisdone [24]

The answer is C.

$0.75(150) = \frac{ s^{2}}{30.25}$

$112.5 * 30.25 = s^{2}$

$3413.125 = s^{2}$

$s = 58.422$

$V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]$ or $V_2 = \frac{1}{3}\pi r^2h$

Step-by-step explanation:

Given

$Ratio = \frac{\pi}{4}$

See attachment for complete question

Required

Determine the volume of the cone

The volume of a square pyramid is:

$V = \frac{a^2h}{3}$

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

$a = 2r$

The volume becomes;

$V = \frac{(2r)^2h}{3}$

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

$V_2 = Ratio * V$

$V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]$

$V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}$

Open bracket;

$V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}$

Cancel out 4

$V_2 = \pi * \frac{r^2h}{3}$

The above can be written as:

$V_2 = \frac{1}{3} * \pi r^2h$

$V_2 = \frac{1}{3}\pi r^2h$

So, we have:

$V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]$

or

$V_2 = \frac{1}{3}\pi r^2h$

pickupchik [31]

Answer:

Beta is 60 degrees, and the angle of A should be 30 degrees.

Step-by-step explanation:

Its a right triangle, so it equals 180 degrees, there's a perpendicular angle at 'C' so its 90 degrees, B and its angle of 'Beta' 60 degrees, and angle 'A' can be 30 degrees. if in need of more explanation please look into complimentary and supplementary angles should give you a good idea.

A calzone is divided into 40 equal pieces.violet and ben ate 1/8 if the calzone on tuesday the next day ben ate 1/5 of the calzo

muminat

Answer:

28 pieces.

Step-by-step explanation:

1/8 of 40 is 5. Subtract that five (the five that they ate) from 40, leaving you with 35. It says the next day, Ben ate 1/5 of what was left. He ate 1/5 of 35 which is 7. He ate 7 pieces. Subtract this from 35 and you're left with 28 pieces of calzone.
