What is the approximate area of a circle with a diameter of 18 m?
Since the question asks for an approximate value, and not an exact value, we can assume that 18 meters is an approximate measurement, and not an exact value. Thus, we can use the formula for the area of a circle: Area = pi * (radius)^2 and then round off the final answer to the amount of significant digits that we put into the formula, the 2 significant digits of 18 m. We only round off the final answer; we try to use as many digits as possible in the steps in between so that we don't introduce errors. For example, to get the radius of the circle, we halve the diameter, so the radius of the circle is 9 meters. We use the formula now by applying order of operations. First we evaluate the exponent by squaring the radius to get 81 square meters. Then we multiply this by a value of pi that has as many accurate digits as possible. I used a calculator to get 254.46900494077325231547411404564 square meters. This is a ludicrous amount of detail from a measurement of only 2 significant digits. Since we only have 2 significant digits of information, we only know that the first two digits of our answer are accurate: 25_.___.... . This means the true area is between 250 and 260 (all the numbers that start with 25_). We do not have enough information to determine the third digit, but since the next digit in our ideal calculation is 4, then if the true diameter is closer to exactly 18.0 meters, then the true area is closer to 250 than 260, so we report the approximate area as 250 square meters.
What is the radius of a 250 sq ft circle?
250 sq.ft. is the area of the circle. Apply the Area eq'n A = pi r^2 Algebraically rearrange r^2 = A/ pi r = sqrt(A/pi) Substituting r = sqrt( 250/3.141592....) r = sqrt(79.57747165...) r = 8.920620581.... ft. r = 8 ft 11.047... inches. ~ 9ft

What is the circumference of a circle with a radius of 250 meters?
The circumference of a circle with a radius of 250 meters is about 1,571 meters. (C = r x 2 x Pi).
What is the circumference of a circle that has a diameter of 250?
Circumference = pi*diameter = 785.4 units.
What is a circumference of a circle whose diameter is 250cm?
Circumference = 250*pi cm
What is a circumference of a circle whose diameter is 250 cm?
The circumference of a circle is calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 250 cm. Therefore, the circumference of the circle would be C = 3.14159 x 250 cm = 785.3975 cm.
If the circumference of a circle is 250 What is the radius?
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
What is the circumference of he velodrome track?
The circumference of a standard velodrome track varies depending on its design, but it typically ranges from 250 meters to 400 meters. Most Olympic-sized velodromes have a circumference of about 250 meters. The track is oval-shaped with banked curves to facilitate high-speed cycling. For precise measurements, it's best to refer to the specific velodrome in question.
