Answer» Answer: UR answer:-hope it's help uStep-by-step explanation: Given: Curved SURFACE Area of cylinder = 264M 2
Volume of cylinder = 924m 3
CSA of cylinder = 2πrh 264 = 2× 7 22
×r×h r×h=42 h= r 42
...(1) Volume of cylinder = πr 2 h 924= 7 22
×r 2 × r 42
924= 7 22
×r×42 r= 22×42 924×7
r=7m. Radius is 7m diameter is 14m Height of cylinder = 7 42
=6m |
