Question

Find the circumference of a circle with a radius of 1.25m. Leave your answer to 1 decimal place and give units.

Answer 1

Answer:

7.8m

Step-by-step explanation:

circumference of circle =2 pi r

=2 × 22/7 × 1.25

=7.8 m

Answer 2

Given :

• Radius of a circle = 1.25 m

To find :

• Circumference of the circle.

Solution :

We know that if we are given the radius of a circle then we can easily find the circumference of the circle using this formula:-

• Circumference = 2πr

★ Here:-

• π = 22/7
• r = radius

★ Substituting the values:-

→ Circumference = 2 × 22/7 × 1.25

→ Circumference = 44/7 × 1.25

→ Circumference = 55/7

→ Circumference = 7.87 m (approx value)

Answer :

• The circumference of the circle = 7.87 m (approximately)
