C=2pir
V=(4/3)pir^3
solve for V

C=31.4
31.4=2pir
divide by 2
15.7=pir
divide both sides by pi or 3.14
5=r

V=(4/3)pir^3
V=(4/3)pi5^3
V=(4/3)pi125
V=(500/3)*3.14
V=523.33333333333333333333333333333

Can someone please help me with this similar area question? I have the answer but I’m not sure how to get to it. Will make brain

Mumz [18]

Step-by-step explanation:

well there is a very simple point that you have mistaken tho:

484cm², 25cm²

Areas are defined in square cm but the radius is in cm

so:

$\sqrt{ \frac{484 {cm}^{2} }{25 {cm}^{2} } } = \frac{7.92}{r} = = = > 4.4 = \frac{7.92cm}{x} = = > x = \frac{7.92cm}{4.4} = x = 1.8cm$

and there you go
