Question

diameter of a circle field is 70 cm . The area of the same circular field will be _____.

Answer 1

Answer:

7700 sq cm

Step-by-step explanation:

d = 70 cm

r = 70/2 = 35 cm

therefore, area = 2 * 22/7 * 35 * 35 = 7700 sq cm

Answer 2

Given :-

• Diameter of circular field = 70cm .

To Find :-

• Area of circular field ?

Solution :-

we know that,

• Radius = Diameter/2
• Area = π * (radius)²

so,

→ Radius od circular field = 70/2 = 35 cm.

then,

→ Area of circular field = (22/7) * 35 * 35 = 22 * 5 * 35 = 110 * 35 = 3850 cm². (Ans.)
