Question

radius of wheel is 28centimetre what is its perimeter​

Answer 1

Answer :-

Step-by-step explanation:

radius = 28cm

formula = 2*pi*radius

2 × 22 × 4 = 96 sq. cm

Answer 2

The perimeter of the wheel is 176 cm.

The perimeter of a circular wheel is equal to its circumference.

We know that, for a circle of radius r, its circumference is given by the formula

C = 2Пr

For the circular wheel of radius = 28cm, its perimeter is given as:

C = 2П(28) cm

= 2*22/7*28       [If П is considered to be 22/7]

=  176 cm
