Find the volume of a cone with a height of 6 in and a base radius of 4 in
Neko [114]

Answer:

The answer is

<h2>100.5 in³</h2>

Step-by-step explanation:

The volume of a cone is given by

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

where

r is the radius

h is the height of the cone

From the question

h = 6 in

r = 4 in

The volume of the cone is

V  =  \frac{1}{3}  \times  {4}^{2}  \times 6\pi \\  =  \frac{1}{3}  \times 16 \times 6\pi \\  =  \frac{1}{3}  \times 96\pi \\  = 32\pi \\  = 100.530964

We have the final answer as

100.5 in³

Hope this helps you

#72 i will give brainliest to the best answer!​
Zarrin [17]

Step-by-step explanation:

Select all of the following that are quadratic equations.

x² + 3x - 5 = 0 ✓

x² - x = 3x + 7 ✓

5x - 7 = 0 X

7x² + 14x = 0 ✓

x³ - 3x² + 1 = 0 X

x - 5 = 9x + 7 X

What is quadratic equations?

Quadratic equations is a equation that has a general form like "ax² + bx = c"

For example :

x² + 3x - 5 = 0

x² + 3x = 5

x² → ax²

3x → bx

5 → c

What is an equation of a line that passes through the point (-3 -7) and it’s parallel to the line 2x-3y=24
andrew-mc [135]

Answer:

y=(-2/3)x-9

Step-by-step explanation:

1) first put the equation in terms of y. You should get y=-(2/3)x-8.

2) parallel lines have the same slope so the slope for this line and the answer should be the same

3) using the form y=mx+b plug (-2/3) in as the slope or m

4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b

5) isolate the variable b and plug in your answer to the equation.
