Question

Find its circumference if diameter of the circle is 56m.

Answer 1

Circumference Of Circle = 176 cm

Step-by-step explanation:

GIVEN

Diameter = 56m

Radius = Diameter / 2 = 56 / 2 = 28 m

___________________________

TO FIND

Circumference Of Circle

___________________________

FORMULAS OF CIRCLE

Diameter Of Circle = 2 × Radius

Radius Of Circle = Diameter / 2

Circumference Of Circle = 2 × π × r

Area Of Circle = π × r²

___________________________

We know that,

Circumference Of Circle = 2 × π × r

Circumference Of Circle = 2 × ( 22/ 7 ) × 28

Circumference Of Circle = 2 × 3.14285714 × 28

Circumference Of Circle = 6.28571429 × 28

Circumference Of Circle = 176

Circumference Of Circle = 176 cm

Answer 2

C≈175.93m

Using the formulas

C=2πr

d=2r

Solving forC

C=πd=π·56≈175.92919m
