Question

find the circumference and area of diameter 5cm​

Answer 1

Step-by-step explanation:

Perimeter of circle = 2 pi r

= 2 × 22 / 7 × 5 / 2

= 110 / 7

= 15.714 cm

Area = pi r²

= 22 / 7 × 5 / 2 × 5 / 2

= 11 × 25 / 14

= 275 / 14

= 19.643 cm²

Answer 2

Step-by-step explanation:

LET ASSUME,

DIAMTER =5cm.

r=d/2

r=5/2

r=2.5cm.

area of circle =πr²

=22/7×(2.5)²

=19.6cm² (approx)

CIRCUMFERENCE OF CIRCLE =2πr

=2×22/7×2.5

=15.714cm (approx)
