Step-by-step explanation:

The volume of a sphere is found by

The radius is 7 so this should give you (4/3)pi(7)^3

(4/3)pi(343)

Hopefully this is the format it is in... Hope this helps :)

1372

Step-by-step explanation:

Volume of a sphere can be found by using the formula V= 4/3 () where r is the radius of sphere.

Thank me or give 5 stars if you learned! Or if it is correct!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

11

step-by-step explanation:

32.50-7.50=25

225/25=11
