Answer:
Step-by-step explanation:
The formula to find the circumference of a circle is :
C = 2 π r
Given that, the circumference of the circle is 149 mm.
First, let us find the radius of the circle.
C = 2 π r
149 = 2 × 3.14 × r
149 = 6.28r
Divide both sides by 6.28.
23.72 = radius
Now let us find the area of the circle.
The formula to find the area of the circle.
A = π r²
Let us find it now.
A = 3.14 × 23.72²
A = 3.14 × 562.6384
A = 1766.7mm²
