6.
14 cm. Find its length.
7. The diameter of a cylinder is 25 cm and height 20​

Answer 1

QUESTION:-

The curved Surface area of a right circular cylinder is 1760cm² and its radius is 6cm. Find its length.

________________________

ANSWER:-

CSA of cylinder = 2πrh

1760 = 2*(22/7)*6*h

1760*(1/2)*(7/22)*(1/6)=h

280/6=h

$\huge{ \red{h \: = \: 46.67 \: cm}}$

Answer 2

Step-by-step explanation:

1) CSA of cylinder = 2πrh

1760 = 2*(22/7)*6*h

1760*(1/2)*(7/22)*(1/6)=h

280/6=h

h=46.67cm

2) CSA of cylinder = 2πrh

⟹CSA=2×22/7 ×12.5×20

⟹CSA= 44/7 × 125/10 ×20

⟹CSA= 44/7 ×125×2

⟹CSA= 11000/7

⟹CSA=1571.4cm2

Therefore , the required curved surface area (CSA) of cylinder is 1571.4 cm²

Hope this is helpful for you.
