The diameter of a circle is 6m. Find its area to the nearest whole number
The radius of the circle is half of the diameter, so:
radius = 6m/2 = 3m
The area of a circle is given by the formula A = πr^2, where π is approximately 3.14. Substituting the values gives:
A = 3.14 x 3^2
A = 28.26
Rounding this to the nearest whole number gives:
A ≈ 28
Therefore, the area of the circle to the nearest whole number is 28 square meters.
