Answer 1

Question,

Find the diameter of circle whose circumference is 12.56 cm(π=3.14).

Answer,

4

Given,

Circumference=12.56

π=3.14

To find,

Diameter

Formulas,

Formula of circumference

$2 \times \pi \times r$

Formula of diameter

$2 \times r$

Solution,

• We use circumference formula,

2×3.14×r=12.56

3.14×r=12.56 ÷ 2

3.14×r=6.28

r=6.28 ÷ 3.14

R=2

• Now,we use daimeter formula,

2×2=4

Hence,the answer is 4.
