Question

Find the circumferences of a circle having diameter 10cm. Take π = 3.14​

Answer 1

Answer:

31.4

Step-by-step explanation:

d=10

radius=d/2

r=10/2

r=5

Circumference=2πr

=2*3.14*5

=31.4

Answer 2

Answer:

• The circumference of the circle is 31.4 cm.

Step-by-step explanation:

Given that:

• A circle having diameter 10 cm.
• We have to take the value of π = 3.14

To Find:

• The circumferences of a circle.

Concept:

• First we have to find the radius of the circle after that we will able to find its circumference by using the formula.

Finding the radius of the circle:

We know that.

Diameter = 2 × Radius

⟶ 10 = 2 × Radius

⟶ Radius = 10/2

⟶ Radius = 5

∴ The radius of the circle = 5 cm

Finding the circumference of the circle:

We know that.

Circumference of a circle = 2π × Radius

⟶ Circumference = 2 × 3.14 × 5

⟶ Circumference = 31.4

∴ The circumference of the circle = 31.4 cm
