Answer 2

Radius = 12 cm

Step-by-step explanation:

Given Data

Circumference of a circle = 75.36 cm

To find - the radius of the circle

Circumference of a circle is defined as the product  of π and diameter of the circle.

Also circumference is defined as the product of 2π and radius of the circle.

Symbol for Circumference of the circle is 'C'.

Circumference of the circle = 2 π r (units)

Substitute the values in above formula, where π = 3.14

75.36 = 2 × 3.14 × r       (cm)

75.36 = 6.28 × r    (cm)

    (cm)

r = 12 cm

Therefore the radius of the circle with circumference 75.36 cm is 12 cm
