Question

THE CIRCUMFERENCE OF THE BAS F A CYLINDER IS 176 CM AND ITS HEIGHT IS 65 M .FIND THE CURVED SURFACE AREA AND TOTAL SURFACE AREA AND TOTAL SURFACE AREA AND TOTAL SURFACE AREA OF THE CYLINDER.

Answer 1

Given that

• Circumference of base = 176cm
• Height = 65 cm

Circumference of circle

$\boxed{2\pi \:r}$

Then; 2πr = 176 cm

r = 176×7/22

r = 8×7

$\huge{r = 56}$

➪CURVED SURFACE AREA OF CYLINDER :-

2πrh

2 × 22/7 ×56 × 65

44 × 8 × 65

22,880 cm²

TOTAL SURFACE AREA OF CYLINDER :-

2πr(r+h)

2 × 22/7 × 56 (56+65)

44 × 8 × 121

42,592 cm²

I hope it helped you ✌.

Answer 2

Answer:

Given that

Circumference of base = 176cm

Height = 65 cm

Circumference of circle

Then; 2πr = 176 cm

r = 176×7/22

r = 8×7

➪CURVED SURFACE AREA OF CYLINDER :-

2πrh

2 × 22/7 ×56 × 65

44 × 8 × 65

22,880 cm²

TOTAL SURFACE AREA OF CYLINDER :-

2πr(r+h)

2 × 22/7 × 56 (56+65)

44 × 8 × 121

42,592 cm²
