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

What is the midpoint between 0.1 and 0.2?

Sonbull [250]

Find the sum of both numbers, then divide by 2. That'll give you the median, not the midpoint, which is what I'm assuming you want to find (since you haven't given me any x-y coordinates).

So (0.1+0.2)/2=0.15

What is the slope of the line y+2=-2(x-3)

muminat

Answer:

m = -2

Step-by-step explanation:

This equation is in point-slope form

The numbers added or subtracted by a variable are a coordinate point.

y + 2 --> (0,-2)

x - 3 --> (3,0)

(3,-2)

The slope is represented by the number outside of the parentheses.

Therefore, the slope of the line is -2

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

Blababa [14]

Answer:

Step-by-step explanation:

so when the height is zero, that's when the rocket hits the ground. The equation will have two zeros, but one would be for a negative time, or before the rocket is launched. so we only one the one after the rocket is launched.

use the quadratic formula to solve for x ( which is time)

-124 +- sqrt [ $124^{2}$ - 4*(-16)*(127) ] / 2 (-16)

-124 +- sqrt [15376 + 8128 ] / -32

-124 +- sqrt [23504 ] / -32

-124 +- 153.310 / -32

if we take the positive part it will become the negative time so skip that one try the negative part 1st

-124 - 153.310 / -32

-277.310 / -32

8.6659 seconds to hit the ground. ( time of flight) aka TOF

8.67 seconds ( rounded to nearest 100th)
