Question

Find the perimeter of a circle whose diameter is 14

Answer 1

$\huge\mathbb{SOLUTION:-}$

$\sf\underline{\pink{\:\:\:\:\:\:\:Given:-\:\:\:\:\:\:\:}}$

● Diameter of circle =14 unit

●Radius =14/2

• =>7unit

• Now the perimeter of circle

$\boxed{\sf{Perimeter\:of\:circle=2\pi r}}$

$\sf\underline{\blue{\:\:\:\:\:\:\:A.T.Q:-\:\:\:\:\:\:}}$

$\sf:\implies Perimeter=2\times \dfrac{22}{\cancel7}\times \cancel{7}\\ \\ \sf:\implies Perimeter=2\times 22\\ \\ \sf:\implies Perimeter=44unit$

$\boxed{\sf{\orange{Perimeter\:of\:circle=44 unit}}}$

Answer 2

Answer:44 cm

Step-by-step explanation:r=d/2

r=14/2

r=7cm

Perimetre of the circle =2×22/7×7

=2×22

=44cm
