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
