Use 3.14 for π to estimate the area of a circle. The diameter is 24.4. Round your answer to the nearest hundredth if necessary.
1. A 22.0 cm
2. D 113.0ft2
3. A 15.9 mm
4. C 1,384.7mm2
Area = π(12.2)^2
= appr 3.14(148.84) = appr 467.36
more accurate answer = π(12.2)^2 = appr 467.59
rather silly to ask for nearest hundredth after asking for approximation.
Well, to estimate the area of a circle, we can use the formula A = πr^2. But instead of using the actual value of π, let's have some fun and use the value you suggested, which is 3.14. So, the radius would be half the diameter, which is 12.2. Now, let's calculate the area using the clown-approved formula: A = 3.14 * 12.2^2. That gives us approximately 470.38. So, the estimated area of the circle is 470.38 square units. Remember, though, this answer is just a playful approximation!
To estimate the area of a circle, you need to use the formula A = πr^2, where A is the area and r is the radius. Since you have the diameter, you need to divide it by 2 to get the radius.
Given that the diameter is 24.4, the radius would be 24.4 / 2 = 12.2.
Next, substitute the value of π as 3.14 and the radius as 12.2 into the formula:
A = 3.14 x (12.2)^2
Calculating this:
A = 3.14 x 148.84
A = 466.0376
Rounding your answer to the nearest hundredth, the estimated area of the circle is approximately 466.04 square units.
To estimate the area of a circle, we can use the formula:
Area = π * (radius)^2
Given that the diameter is 24.4, we can calculate the radius by dividing the diameter by 2:
Radius = diameter / 2 = 24.4 / 2 = 12.2
Using the value of π as 3.14, we can substitute these values into the formula:
Area ≈ 3.14 * (12.2)^2
Calculating this, we get:
Area ≈ 3.14 * 148.84
Area ≈ 466.5544
Rounding to the nearest hundredth, the estimated area of the circle is approximately 466.55 square units.
