Answer:

12

Step-by-step explanation:

Simplify  \frac{4}{5}G

​5

​

​4

​​ G  to  \frac{4G}{5}

​5

​

​4G

​​ .

\frac{4G}{5}+42=2.8G+18

​5

​

​4G

​​ +42=2.8G+18

Multiply both sides by 5.

4g + 210 = 14g + 90

Simplify  

 14G + 90 - 4G to 10G + 90

Subtract 90 from both sides.

210-90=10G210−90=10G

Simplify  210-90210−90  to  120120.

120=10G120=10G

Divide both sides by 1010.

\frac{120}{10}=G

​10

​

​120

​​ =G

Simplify  \frac{120}{10}

​10

​

​120

​​   to  1212.

12=G12=G

Switch sides.

G=12G=12

SORRY ABOUT ALL THIS WORK...

What is the volume, in cubic ft, of a cylinder with a height of 12ft and a base radius of 9ft, to the nearest tenths place
velikii [3]

Answer:

3054.0ft³

Step-by-step explanation:

Given parameters:

Height of cylinder  = 12ft

Base radius  = 9ft

Unknown:

Volume of the cylinder = ?

Solution:

The volume of a cylinder is the product of its base area and height;

  Volume of cylinder  = base area x height

                                   = πr²h

r is the radius

h is the height

Insert the parameters and solve;

            v = 3.142 x 9² x 12  = 3054.0ft³

A= 89cm root 2 square
Serga [27]

Considering the given area of the square, it is found that it's side length is an irrational number.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on a search engine, it asks if the side length of the square of area 89 cm² is rational or irrational.

<h3>What is the formula for the area of a square?</h3>


The area of an square of side length s is given by s squared, as follows:

A = s².

In this problem, the area is of 89 cm², hence:

s² = 89.

s = sqrt(89).

The square root of 89 is a non-exact root, hence it cannot be represented by fraction and is an irrational number.

What is the radius of the circle shown below (and how did you solve it)?
natulia [17]
So you rearrange it as two separate equations to complete the square so 
(x-6)^2 -36 + (y-3)^2 - 9 +9 = 0
then move the integers to the other side so its in the right format for the equation of a circle and root it
so radius is 6
