Find the volume of a right circular
cylinder of height 4cm, whose
curved surface area is 176 sq.cm
Answers
Answer:
c.s.a=2πrh
176=2*22/7*r*4
176=44/7*4r
176*7/44=4r
4r=28
r=7
then,
volume of cylinder=πr*square*h
=22/7*7*7*4
=154*4
=616
Answer:
GIVEN :
height of the cylinder : 4cm
curved surface area {CSA}: 176cm²
curved surface area:2πrh
176 =2×22/7×r×4
176 = 44/7×4r
4r = 176×7/44
4r = 28
r = 28/4= 7cm
volume of the cylinder: πr²h
= 22/7×7×7×4
= 154×4
= 616cm³
answer : 616cm³
Step-by-step explanation:
at first write the given
next write down the CSA formula : 2πrh
now evaluate 176= 2× 22/7×r×4
176 = 44/7 × 4r
4r=176×7/44
4r = 28
r= 28/4= 7
now find the volume of the cylinder : πr²h cubic m
= 22/7×7×7×4
= 154×4
= 616cm³
