Question

If the circumference of the base of a right circular cylinder is 220cm, find the radius.

Answer 1

Answer:

Step-by-step explanation:

Circumference of cylinder is 2pie r

Circumference is 220cm

2×22/7×radius =220

Radius =35 cm

Answer 2

$\huge\underline\mathrm{SOLUTION:-}$

AnswEr:

• The radius of the circle = 35 Cm

Given That:

• circumference of the base of a right circular cylinder is 220cm.

Need To Find:

• Radius of the circle = ?

ExPlanation:

Formula used here:

• Circumference of the circle = 2πr

Putting the values according to the given formula:

➠ 200 = 2 × $\mathsf {\frac{22}{7} \times Radius}$

➠ 10 = × $\mathsf {\frac{22}{7} \times Radius}$

➠ Radius = 5 × 7

➠ Radius = 35

➠ ${\underline{\boxed{\sf{Radius = 35\:Cm}}}}$

ThereFore:

• The radius of the circle = 35 Cm

Additional Information:

What is Radius?

• Radius is a line segment joining the centre of a circle to any point on the circle.

• $\mathsf {Radius = \frac{1}{2}\: Diameter}$

What is Circumference?

• Perimeter of a circle is called the circumference of the circle.

• Circumference of the circle = 2πr
