Question

Find a volume of cylinder based on perimeter 66cm and height 40cm

Answer 1

Circumference  C=2πr= 66cm  R = 66 * 7 ÷ 2 * 22 r= 10.5 cm   area of base = pie *  r^2                         = 22 /7 * 10.5 * 10.5                         =  346.5 cm^2    volume = base * height              = 346.5 * 40               = 13860 cm^3    #hope it helps #Mark as the brainliest pls . 

Answer 2

We are given the circumference of the base. So, we can calculate the r 2πr=2*22/7*r 66=2*22/7*r 66/2=22/7*r 33*7=22*r 231=22r r=10.5cm  Volume of cylinder = πr²h V=3.14*(10.5)²*40 V=3.14*110.25*40 V=13847 (approx) (If the value of π is taken 22/7 then the answer is 13860)
