Question

Find the circumference and area of each circle of radius is=to 3.5 CM

Answer 1

Heya...
Here is your answer -----

________________________

CIRCUMFERENCE ----
________________________

=> Circumference = 2 × π × r

=> Circumference = 2 × 22/7 × 3.5

=> Circumference = 2 × 22 × 0.5

=> Circumference = 44 × 0.5

=> Circumference = 22 cm
________________________

AREA -----
________________________

=> Area = π × r^2

=> Area = 22/7 × 3.5^2

=> Area = 22/7 × 12.25

=> Area = 22 × 1.75

=> Area = 38.5 cm^2

Answer 2

Heya!

Radius= 3.5cm
Circumference= 2×π×r
=2×22/7×3.5
=22cm

Area= πr^2
=22/7×3.5×3.5
=38.5cm^2


Hope it helps...!!!
