Question

FIND THE CIRCUMFERENCE OF A CIRCLE WHOSE DIAMETER IS 14 CM

Answer 1

The circle's circumference is 43.96 cm

Step-by-step explanation:

A diameter is the straight line drawn from one point on the circle to other point on the circle such that the line passes through origin.

Radius will be the line drawn from the circle's centre to the point on the circle.

Radius will be half of the diameter.

Given the diameter of the circle = 14 cm

Then, radius of the circle = 14/2 = 7 cm

Circumference of the circle is the perimeter of the circle. It is the length of the circle.

The circumference = 2Πr

Circumference = $2 \times \pi \times 7$

$=14 \times \pi$

$=14 \times 3.14$

The circle's circumference = 43.96 cm

Answer 2

Answer:

$Circumference \:of \: the\\ circle (C) = 44\:cm$

Step-by-step explanation:

$Given \: diameter \: of \\a \: circle (d) = 14\:cm$

$Circumference \:of \:a \: circle (C) = \pi d \\=\frac{22}{7}\times 14\:cm\\=22\times 2\\=44\:cm$

Therefore,

$Circumference \:of \: the\\ circle (C) = 44\:cm$
