A circle has a diameter of 28 centimeters.
Estimate the area of the circle. Use
22
7
for
π
.
What you need is knowing how to do it, the answer is an afterthought.
Area = π r^2
your radius is 14 cm, so what is
π (14^2) ?
i need the answer to this question
To estimate the area of a circle, we need to use the formula A = πr^2, where A is the area and r is the radius of the circle.
1. First, find the radius of the circle. We know that the diameter is 28 centimeters, so we can divide it by 2 to get the radius: r = 28 cm / 2 = 14 cm.
2. Now, plug the value of the radius into the formula A = πr^2. We are given to use 22/7 for π:
A = (22/7) * (14 cm)^2
3. Simplify the calculation:
A = (22/7) * (196 cm^2)
A ≈ 616 cm^2
Therefore, the estimated area of the circle is approximately 616 square centimeters.
