Answer 1

Answer:

If the diameter of a car wheel is 112 cm, then its circumference equals:- 352cm

Answer 2

Answer:

• Circumference of the circle is 352cm.

Step-by-step explanation:

Given:

• Diameter of a car wheel is 112cm.

To Find:

• Circumference of the car wheel.

Solution:

According to the question, diameter is given and we are said to find circumference of the car wheel.So,we will firstly find the radius of the circle and as we know that radius of the circle is 2 multiple of diameter and after getting the value of radius then we will eligible for find circumference of the car wheel.

we have,

• Diameter = 112cm

As we know that,

>>Radius = Diameter/2

.Radius = 112/2

.Radius = 56cm.

___________________________

After getting the value of radius then now find the value of circumference of the car wheel.

we have,

• radius = 56cm
• π(22/7)

As we know that,

>>Circumference of the circle = 2πr

. Circumference = 2 ×22/7 × 56

. circumference = 352cm.

______________________________

$\therefore$ Hence, circumference of the circle is 352cm.
