Answer 2

Answer:

GIVEN RADIUS OF A CIRCLE=10cm

THEN DIAMETER OF THE CIRCLE=10×2=20

THEN PERIMETER OF THE CIRCLE=2πr

=2×22/7×10(HERE INSTEAD OF TAKING 22/7 I WILL TAKE 3.14)

=2×3.14×10

=2×31.4

=62.8cm

$then \: area \: of \: the \: circle = \pi {r}^{2}$

$= 22 \div 7 \times {10}^{2} (here \: instead \: of \: taking \: 22 \div 7 \: i \: will \: take \: 3.14)$

$3.14 \times 100 = 3.14 \: {cm}^{2}$
