Question

the volume of a cylinderical can is 4224cm^3 and it's height is 21 cm find its radius​

Answer 1

CYLINDER = VOLUME FORMULA = PIE*r²*h

so according to the question volume is given

value of Pie is = 3.14

= 4224= 3.14*r²*21

= r=

$\frac{ \sqrt{4224 } }{3.14 \times 21}$

= √64.05

= 8.00

so the radius is 8.00cm .

hope it helps you .
