Question

The circumference of the base of a right circular cylinder is 220 cm. If the height of the cylinder is 2 m,find the lateral surface area of the cylinder. Plzz answer fast and if the answer will be correct i will mark u as brainlest answer!!

Answer 1

Answer:

4.4 m² or 44000 cm²

Step-by-step explanation:

LSA of a cylinder = Circumference of the base × Height of the cylinder

(in cm²)

LSA= 220 × 200

=44000 cm²

(in m²)

LSA= 2.2 × 2

=4.4 m³

Answer 2

$\huge \underline \mathsf \red {Solution:-}$

Let the height and radius of the cylinder be h and r cm respectively.

Given:

• Height is 2m = 200cm

As, circumference of base = 220

2πr = 220

➠ $\mathsf {2 \times\frac{22}{7} \times r = 220}$

r = 35 cm

➠ $\mathsf {2 \times\frac{22}{7} \times 35 \times h}$

➠ $\mathsf {2 \times\frac{22}{7} \times 35 \times 220}$

As, Lateral surface of cylinder = 2πrh

= 44000 cm²
