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

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?
radius = diameter ÷ 2 area_circle = π x radius2 = π x (20 cm ÷ 2)2 = 100π cm2 ≈ 314 cm2

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. :)
What is the radius of a circle that is 7.1 cm?
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
