Question

If the circumference of the base of a right circular cylinder is
220 cm, then find its base area.

Answer 1

Answer:

• The base area of the cylinder is 3,850cm²

Step-by-step explanation:

Given that, Circumstance of a base of a right circular cylinder is 220cm. Find is area

Step 1 :

Finding it's radius :

Base of a cylinder is circular in shape.

We know that,

Circumstance of a circle = 2πr

But, the circumstance is 220 (given)

So,

→ 220 = 2 × $\sf \dfrac{22}{7}$ × r

→ $\sf \dfrac{220 \times 7}{44}$ = r

→ r = 35

Radius of its base is 35cm.

Step 2 :

Finding it's base area :

Since, base of the cylinder is circular-shape

Area of a circle is given by :

→ πr²

• r (radius) = 35cm.
• Taking ‘π’ as $\sf \dfrac{22}{7}$

So,

→ $\sf \dfrac{22}{7}$ × (35)²

→ 22 × 5 × 35

→ 3850cm²

The base area of the cylinder is 3,850cm² ✔
