Question

the height of cylinder is 25 cm and the area of a square centimetre find the area of the total surface of the cylinder​

Answer 1

Answer:

Hi friend,

Base area of cylinder = Tr²

25 = 22/7 xr²

r² = 25×7/22 = 7.9

r² = 7.9

r = √7.9 = 2.8 cm

Volume of cylinder = r²h

400 = 22/7 x 2.8 x 2.8 x h

H = 400 × 7/22 x 2.8 x 2.8

X

H = 2800/172.48

H = 16.2 CM

Hence,

Height of the cylinder = 16.2 cm

Answer 2

Answer:

Base area of cylinder = πr²

25 = 22/7 ×r²

r² = 25×7/22 = 7.9

r² = 7.9

r = ✓7.9 = 2.8 cm

Volume of cylinder = πr²h

400 = 22/7 × 2.8 × 2.8 × h

H = 400 × 7 / 22 × 2.8 × 2.8

H = 2800/172.48

H = 16.2 CM

Hence,

Height of the cylinder = 16.2 cm
