Answer: 5a-7

Explanation: If you distribute properly you should subtract 6a-1a to get 5a then you have to add -14 and 7 together to get -7 and when you place 5a and -7 together it creates 5a-7

Help me to solve this problem

anyanavicka [17]

Here,

Volume of cylinder = 539^3 cm

Circumference = 22 cm

Height = ?

Now,

Circumference = 2πr

or, 22 = 2*22/7*r

or, 22 = 44/7*r

or, 154/44 = r

◆ r = 3.5 cm

Then,

Volume of cylinder = πr^2h

or, 539 = 22/7*(3.5)^2*h

or, 539 = 22/7*12.25*h

or, 539 = 269.5/7*h

or, 3773 = 269.5*h

or, 3773/269.5 = h

◆ h = 14 cm

I hope it's help you...

I hope you understand...
