In reference to a circle the value of π is equal to
a. area/circumference
b. area/diameter
c. circumference/diameter
d. circumference/radius

Solution:

We know that

Circumference of a circle = 2πr

As diameter = 2r

Circumference = π × Diameter

π = Circumference/Diameter

Therefore, the value of π is equal to circumference/diameter.

✦ Try This: 4 hectare = ____ cm²

We know that

1 hectare = 10,00,00,000

So we get

4 hectare = 40,00,00,000

Therefore, 4 hectare = 40,00,00,000 cm²
