Question

find the circumference whose diameter is 300mm with pie=3.14​

Answer 1

circumference=

$2\pi \: r$

circumference=2 X 3.14 x 150

=942

Answer 2

Answer:

$\huge{\bold{\underline{\red{Solution ✍:}}}}$

Given:-

diameter $\implies$ 300mm

Then, Radius $\implies$ 150mm

π $\implies$ 3.14

To Find:-

circumference $\implies$ ?

Solve:-

we know that ,

circumference of the circle = 2πr

Now,

$\implies$circumference of the circle = 2 × 3.14 × 150mm

$\implies$circumference of the circle = 2.68 × 150mm

$\implies$circumference of the circle = 402mm✔️
