Question

Find the area of a circle whose diameter is 1.8 m

Answer 1

Answer:

The area of a circle with diameter 1.8 is 2.545

Step-by-step explanation:

Area of a cicle in terms of radius:

Area = π . r2 = 3.14 × 0.92 = 2.55 square m.

In terms of diameter:

Area = π . (d/2)2 = 3.14 × (1.8/2)2 = 3.14 × (0.9)2 = 2.55 square m.

In terms of circumference:

Area = C2/(4π) = 5.662/4π = 31.98/(4 × 3.14) = 31.98/(12.56) = 2.545 square m.
