What is the area of a circle with a circumference of 10 pi?
Using 3.14 as Pi the area of circle is: 0
How do you find the perimeter and area of a circle?
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
What is the circumference of a circle whose area is 100 pi?
The formula for finding the area of a circle is pi times the radius squared. Let's find the radius of the circle. 100 pi/ pi= 100. Squarerooted, the radius is 10. The formula for finding the circumference of a circle is 2 times pi times the radius. So, plug in: 2 times pi times 10 equals 20 pi! Your final answer: 20 pi (or, if you use decimals, approximately 62.8)
Surface area of cone?
(pi times radius squared) plus (pi times radius times slant).
What does pi radius 2 mean?
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
What is pi times the square root of 25 divided by sin 30?
750
What is 25 divided by pi?
25/pi = 7.957747155
What is the circumference of a circle that has 25 as its radius?
157.079632679 :) you have to do the radius x 2 then times that by pi!
What is the area of the circle if the radius is 5?
The area of a circle is equal to pi times the radius squared. So in your case it would be 5 squared, (25) times pi which is equal to ~78.5
What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
A semi circle has a diameter of 10 cm the perimeter is 25 point 7 rounded how do you get that answer?
half times pi times 10....
How do you find the circumfrance of a circle whose radius is 4?
The circumference of a circle is twice the radius times PI [2*pi*r] with r = 4 >> about 25
What is the volume of a cylinder that has a base area of 10 pi cm square and height of 25 cm?
The volume of a cylinder is the area of its base times its height. 10 pi square centimeters * 25 centimeters = 250 pi centimeters cubed = 785.398 centimeters cubed
What is the area of a circle with a circumference of 10 pi?
Using 3.14 as Pi the area of circle is: 0
Is 2 times 3.14 a rational Number?
Yes. 2 x 3.14 = 6.28 = 6 7/25 = 157/25 which is rational. If you are using 3.14 as an approximation to {pi}, then 2 x {pi} is not rational.
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
What is the value of pi of 25 decimal place?
pi = 3.1415926535897932384626434 (to 25 decimal places)
