Question

find the circumference of the circle whose diameter is 10.5 m​

Answer 1

Answer:

Circumference of circle =2πr

2×22/7×105/20 as r=d/2

Answer 2

✔️✔️heyy mate!✔️✔️

here is ur answer....

Using the formulas,

Circumference = 2πr

we know that,

diameter=2r----------(i)

Now,

circumference=π x 2 x r

circumference= 2rπ

circumference = πd ...........from equation (i)

C= πd =π· x 10.5 ≈ 32.89672
