AVprozaik [17]

Answer:

x=8

Step-by-step explanation:

7+5x

so basically what you have to do is take the 7 and subtract from both sides

so like this: 7-7 is 0 so that cancels then 47-7 is 40

then you take 5x and divide 40 by 5

so x=8

hope this helped!

find the volume of the following figure round your answer to the nearest tenth if necessary and make sure to use pi

Vikki [24]

Answer:

524cm^2

Step-by-step explanation:

Formula for Volume of sphere= 4/3 πr^2

We have,

r=5cm

Now,

Volume(v)=4/3 πr^2 = 4/3π 5^3= 4/3π 125 = 166.666666667π = 523.598775599

Rounding to the nearest tenth,

Volume=524cm^2
