Question

If the circumference of a circle is 176cm, find its radius.​

Answer 1

Answer:

r=C/2π

Step-by-step explanation:

So, radius= Circumference÷2π

Circumference= 176cm

π= 3.14159

2xπ= 2x3.14159= 6.28318

= 176/6.28318

= 176÷6.28318

= 28.0112936443

So, Radius= 28.0112936443

Answer 2

Given:-

• Circumference of a circle is 176 cm.

To find:-

• Radius of a circle.

Solution:-

Here,

• Circumference = 176 cm.

Let,

• the radius of a circle be r.

Let's do it,

★Circumference of circle = 2πr

→ 176 = 2 × 22/7 × r

→ 44/7 × r = 176

→ r = 176/1 × 7/44

→ r = 28 cm

Hence,

• the radius of a circle is 28 cm.

Verification:-

→ 2 × 22/7 × 28

→ 1232/7

→ 176

Hence Verified
