Question

If radius of a circle is 10 cm what is the diameter circumference and area of the circle

Answer 1

RADIUS = 10cm

DIAMETER = 2 * RADIUS

DIAMETER = 20 cm

CIRCUMFERENCE = C = 2πr

CIRCUMFERENCE = C = 62.83 cm

AREA OF CIRCLE = A = πr^2

AREA OF CIRCLE = A = 314.16

HOPE THIS ANSWER HELPS YOU

Answer 2

Answer:

Diameter 10×2=20 cm

Circumference = 2×pi×r

= 2×3.14×10

= 3.14×5

= 15.7 cm (approx)

= 15.71428 cm (real)

Area = pi×r^2

= 3.14×10×10

= 3.14×100

= 31.4 cm (approx)
