Question

Find the diameter of cylinders when Volume 704cm³,height 14cm

Answer 1

πr^2h = 704

d^2 = 704 × 1/14 × 7 / 22 × 4

on solving we get ,

d = 8

Answer 2

Answer:

8 cm.

Step-by-step explanation:

Volume of cylinder = πr²h , where h is the height, pi is 3.14159265 and r is the radius.

704 cm³ = 3.14159265*r²*14

$\frac{704 cm^{3}}{14*3.14159265}$ = r² = approx 16 cm²

Therefore radius = 4 cm.

Therefore diameter = 8 cm.
