What is the area of a circle with a radius of 28 cm Use the approximation of 22 by 7 as pie?
Area = 22/7*282 = 2464 square cm
What is the circumference of a circle if the radius is 4.4 cm?
Work it out the circumfrance of a circle is pie x the diameter!
Which is the area of a circle whose circumference is 12 pie centimeters?
If the circumference is 12*pi (not pie!) cm, then the diameter is 12 cm so that the radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 sq cm (approx).
If the circumference is 80 cm on a circle then what is the diameter?
you do 80 divided by 2 divided by (pie) 3.14 wich gives you the radius..and then times the radius by two..
What is the area of a circle with a radius of 13.25?
Main Answer: To find out the area of the circle you must square the radius. Here's the answer: I took pie as 3.141592 Area = pie x radius squared A = pie x 13.25 squared --> pie x (13.25 x 13.25) A = 551.5457455 Don't forget to put the units on (e.g. mm, cm, etc) and round to whatever number of decimal places this question asks for. Extra Info: Circumference of a circle = pie x diameter Area of a circle = pie x radius squared C herry pie's d elicious --> C = pie x d A pple pie's r 2 --> A = pie x r2
What is the circumference of a circle with a 10 cm radius?
about 314
What is the area of a circle with a radius of 28 cm Use the approximation of 22 by 7 as pie?
Area = 22/7*282 = 2464 square cm
What is the diameter of a circle whose area is 314 cm square?
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
The area of a circle is 28point26 square centimeters What is its diameter use pie?
pi x radius2 = 28.26 square centimeters Rearrange the formula to find the radius: radius = the square root of (28.26 divided by pi) radius = 2.999239468 cm diameter = 2 x radius = 5.998478935 cm Therefore the diameter of the circle is 5.998478935 cm or 6 cm correct to the nearest cm.
A cylinder has a radius of 2cm and height of 5cm work out the volume of cylinder in terms of pie?
20 pie cm^3
What is the circumference of a circle if the radius is 4.4 cm?
Work it out the circumfrance of a circle is pie x the diameter!
What is the area of a 20 cm cercle to the nearest cm-squared?
If 20cm is the diameter then radius is 10cm and area = Pi * r2 = Pi * 100 = 314 to the nearest square centimetre.
Which is the area of a circle whose circumference is 12 pie centimeters?
If the circumference is 12*pi (not pie!) cm, then the diameter is 12 cm so that the radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 sq cm (approx).
If the circumference is 80 cm on a circle then what is the diameter?
you do 80 divided by 2 divided by (pie) 3.14 wich gives you the radius..and then times the radius by two..
What is the area of a circle whose diameter is 20 cm?
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is 20 cm, the radius would be half of that, which is 10 cm. Plugging in the radius into the formula, we get A = π(10)^2 = 100π cm^2. Therefore, the area of the circle with a diameter of 20 cm is 100π square centimeters.
What is the area of a circle with a radius of 13.25?

How do you findArea of a circle?
well the formula to find the area of a circle is Area=pie x radius squared so if i say calculate the area of a circle with the following measurements giving your answer in terms of pie. Radius=8cm Area=pie x radius squared Area=pie x 8 squared Area= 64 pie cm squared If you do this calculation on your calculator ( pie x 8 squared) you should get the same answer. I hope this helped. If you need anything else veryfying then please ask. :)
