Question

the circumference of base of a cylinder is 176 cm and its height is 15 cm,its curved surface area will be *​

Answer 1

Sólution:-

• Given:

➤Circumference=176cm

➤Height (h)=15cm

• Therefore:

$➵2\pi r = 176$

$➵2 \times \frac{22}{7} \times r = 176$

$➵ \frac{44}{7} \times r = 176$

$➵r = 176 \times \frac{7}{44}$

$➵r = 28cm$

➤Radius (r) =28cm

• Now:

We know,curved surface area of cylinder=2πrh u²

• Therefore:

Curved surface area of this cylinder=

$⇥2 \times \frac{22}{7} \times 28 \times 15 {cm}^{2}$

$⇥2640 {cm}^{2}$

• Hence curved surface area is 2640cm²
