Hey there,
The equation for the volume of a cylinder is V = πr²h.
The first step into finding the radius is to plug in what you already know into the equation:
770 = πr²5We divide both sides by 5:
154 = πr²Now we divide both sides by π:
49.0197224723 = r²Finally we just do the square root of 49.0197224723:
7.0014086063 = rThe radius therefore would be about 7cm.
Hope I helped,
Amna

Divide the numerator by the denominator.
Write down the whole number answer.
Then write down any remainder above the denominator.
