Question

If radius of a circle is 14 cm. find the area and circumference of the circle. ​

Answer 1

Step-by-step explanation:

$Radius = 14cm \\ Circumference = πr \\ ⇒2 \times 22 \div 7 \times 14 \\⇒2 \times 22 \times 2 \\⇒44 \times 2 \\∴ 88cm$

$\huge{\fbox{\pink{Given:-}}}$

Radius of the circle:- 14 cm.

⠀

$\huge{\fbox{\pink{To find:-}}}$

• Area of the circle.
• Circumference of the circle.

⠀

$\huge{\fbox{\pink{Solution:-}}}$

Area of the given circle:-

$area \: of \: the \: circle = \pi {r}^{2} \\ \implies area \: of \: the \: circle =\pi {(14)}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \implies area \: of \: the \: circle = \frac{22}{7} \times 14 \times 14 \\ \implies area \: of \: the \: circle =616 \: {cm}^{2} \: \: \: \: \: \: \: \: \: \: \:$

⠀

Circumference of the circle:-

$circumference \: of \: a \: circle = 2\pi r \\ \implies \: circumference \: of \: a \: circle = 2\pi \times 14 \: \: \: \: \: \: \: \: \\ \implies \: circumference \: of \: a \: circle =2 \times \frac{22}{7} \times 14 \\ \implies \: circumference \: of \: a \: circle =88 \: cm \: \: \: \: \: \: \: \: \: \: \: \: \:$

⠀

$\huge{\fbox{\pink{Formulae Used:-}}}$

$\star \: area \: of \: a \: circle \: = \: \pi \: {r}^{2} \\ \\ \star \: circumference \: of \: a \: circle = 2\pi r$
