What is pi times r2?
pi times radius or diameter equals are of a cirlce
The radius of a circle is 5 inches What is the circumference of the circle?
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
What is Pi times radius times radius?
The answer is Pi times radius squared. Although you can't know anymore since you don't give what the radius is. Although, Pi can be simply referred to as 3.14
How do you find the diameter of a cylinder from the area of the base?
The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.
Is the circumference greater than the diameter?
No. Circumfrence=2 times pi times radius. And since the daimeter = 2 times radius, circumference is diameter times pi.
What is the diamter of a circle 128 circumference?
diameter = 128/pi
How many inches around is a 60 inch table?
circumference = 2 times pi times r OR pi times d diameter = 60 inches pi = 2.1415927 circumference = 2.1415927 x 60 = 128.4956 inches (approximately 128 1/2 inches)
What is the diameter of a circle if circumference is 128 feet?
128 divided by pi (approx. 3.1415927) = about 40.743 feet.
What is 128 as a power of 2?
Express 2 times 128 times 32 times 16 as an exponent of two
What times 4 128?
It is: 32 times 4 = 128
What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
What times 4 equal 128?
It is: 32 times 4 = 128
What is the total surface area of a cylinder with a radius of 4 and a height of 12?
It is: (2*pi*16)+(12*pi*8) = 128*pi square units
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
