Question

if thecircumference of a circle is 308 mm, find the area of the circle

Answer 1

Step-by-step explanation:

2π X r = 308

227x r = 154 154 x 7 22 = r r = 49

area = π X ² 22÷7 × 49²

22÷7 × 2401

22 × 343

7546cm²

here is is solution

Answer 2

Answer:

Let the radius of the circle be r cm

Circumference of the circle=308

Therefore,

2πr=308

$r = \frac{308 \times 7}{2 \times 22}$

r=49m

Therefore,

Area of the circle=π×(49)²

$= \frac{22}{7} \times 2401$

=7546m²
