Question

What is the circumference of the pizza whose diameter is 30 cm ?

Answer 1

Answer:

R=15cm

Circumference is = 2πr=94.2477796077cm

Answer 2

The circumference of the pizza whose diameter is 30 cm is 94.25cm.

Given, the diameter of pizza is = 30cm.

We know, radius = diameter/2

For the pizza of 30cm diameter, its radius is = 30cm/2 = 15cm

For a circle of radius r, its circumference is = 2Пr

So, for the pizza of radius 15cm, its circumference is = 2*П*15 cm

= 30П cm

= 94.25cm                 [П = 3.14 approx]
