Question

the curved surface area of a cylinder is 176 CM square and its area of the base is 38.5 CM square find the volume of the cylinder take Pi is equal to 22 upon 7

Answer 1

Hlw mate!!


base area =38.5sqcm
πr²=38.5
r²=38.5*7/22
r²=(7/2)²
r=7/2 cm--(1)
csa of the cylinder = 2πrh---(2)
given csa =176cm----(3)
(2) =(3)

2*22/7*7/2*h =176

22h=176
h=176/22
h=8cm

volume = πr²h

= 22/7* 7/2*7/2*8
=308cm³

Hope it helpful

Answer 2

Step-by-step explanation:

Base area of cylinder =πr

2

=38.5cm

2

(Given)

⇒πr

2

=38.5

⇒r

2

=

22

38.5×7

⇒r=

12.25

=3.5cm

CSA of cylinder =2πrh=176cm

2

(Given)

∴2πrh=176

⇒h=

2×22×3.5

176×7

=8cm
