Question

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

Answer 1

Answer:

hello your answer is 33

Step-by-step explanation:

d=10.5

r=10.5/2=5.25

circumference= 2×pi×r

2×22/7×5.25

33.0=33

Answer 2

Answer:

• 33m is the required circumference of the circle.

Step-by-step explanation:

According to the Question

It is given that,

• Diameter of Circle = 10.5 m

we have to calculate the circumference of the circle whose diameter are given

Radius = Diameter/2

Radius = 10.5/2

Radius = 5.25 m

Now, calculating the circumference of the circle .

• Circumference = 2πr

On substituting the value we get

↠ Circumference = 2 × 22/7 × 5.25

↠ Circumference = 44/7 × 5.25

↠ Circumference = 44×0.75

↠ Circumference = 33 m

• Hence, the circumference of the circle is 33 m.
