# 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
