HELP URGENT!!!!!!!!!!!!!!!!!!!!!!!!
r-ruslan [8.4K]

Answer:

The equation has an Inifinite amount of solutions

Step-by-step explanation:

2 ( 3g + 2 ) = 1/2 ( 12g + 8 )

First use the distributive property of multiplication -

6g + 4 = 6g + 4

6g cancels out from both sides of the equation -

4 = 4

When both sides of an equation are the same there is an infinite amount of solutions.

Hope this helped! :)

What is the volume of a cylinder in cubic feet with a height of 8 feet and a base diameter of 18 feet
postnew [5]

Answer:

The volume of a cylinder:

V \approx 2035.75 ft^3

Step-by-step explanation:

-To find the volume of a cylinder, you first need the formula:

V = \pi (\frac{d}{2})^2  h

d = diameter

h = height

-Use the following diameter and height for the formula:

V = \pi (\frac{18}{2})^2  8

-Then, you solve:

V = \pi (\frac{18}{2})^2  8

V = \pi \times (\frac{18}{2})^2 \times  8

V = \pi \times (9)^2 \times  8

V = \pi \times 81 \times  8

V = \pi \times 648

V = 648\pi \approx 2035.752

-Since the hundredth place is 2, It cannot be rounded to the nearest hundredths place, so it would be:

V \approx 2035.75 ft^3
