Question

Find the perimeter and area of the figures given below. (π = 22/7) 3.5cm,6 cm​

Answer 1

Step-by-step explanation:

(1) Diameter of the circle is 3.5 cm.

Circumference of a circle = 2πr

Or circumference = πd

Circumference = π × 3.5 cm

= 227×3.5 = 22×0.5 (Taking π=227)

= 11 cm

∴ Circumference of the circle is 11 cm.

(2) Diameter of the circle is 6.3 m.

Circumference = πd

Circumference = π × 6.3 m

=227×6.3 = 22×0.9 (Taking π=227)

= 19.8 m

∴ Circumference of the circle is 19.8 m .

(3) Diameter of the circle is 0.14 m.

Circumference = πd

Circumference = π × 0.14 m

= 227×0.14 = 22×0.02 (Taking π=227)

= 0.44 m

∴ Circumference of the circle is 0.44 m.

Answer 2

Step-by-step explanation:

this not square root because its cm was no length and breadth
