You cannot calculate pi with a radius, but pi as a constant is 3.14159265358979323846, and continues on as an irrational number. If you are trying to calculate the area of a circle, the formula is pi X R squared. If R = 5, the the are is 25 X pi.<br><p></p><p>

Area of circle with radius of 5?
A=pi times R squared If the radius is 5, the area is 25pi
What is the area of a cirle with a radius of 5 in?
The area of a circle of radius r is pi*r*r
The radius of the circle is 5inches what is the circumference?
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
What is the radius 2.6 in in pi?
A radius is not part of pi.
What is radius and diameter if the circumference is 37?
Circumference / pi = Diameter, radius = diameter / 2 So> 37 / pi = 11.777 diameter = 5.8885 radius * * * * * If you wish to give your answer to 5 significant figures, you MUST use the value of pi to at least that many sig figs. Thus, radius = 37/(2*3.1416) = 5.8887 - to 5 sig figs.
What fraction of the area of a circle of radius 5 lies between concentric circles of radius 3 and 4?
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
What is the radius of a cylinder with a radius of 1cm and a height of 5cm?
The radius is in the question 1cm the volume is pi * R^2 * H = pi *1 ^ 1 * 5 = 5 * pi surface area pi * 2 * R * 5 + 2 * ( pi * r ^2) = 10 * pi + 2 * pi = 12 * pi
What is the radius of a circle that has a circumference of 31.4?
circumference = 2*pi*radius. If we round pi to 3.14, the radius is 31.4/(2*3.14)=5.
What is the cicrumference of a circle with a radius of 5 inches?
Circumference: 2*pi*5 = 10*pi inches
If you have a 5 km radius what is the area in unit of square km?
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
How many square inches in a 5 circle?
For a circle, the area is pi x radius squared. If 5 is the diameter, divide it by 2 first to get the radius. Pi is about 3.14.
Area of circle with radius of 5?
A=pi times R squared If the radius is 5, the area is 25pi
What is the circumfrance of a circle with the radius of 5?
circumference = 2*pi*5
What is the area of a circle with a radius r 5?
A = Pi*r2 = Pi*52 ≈78.54
What is the radius of a circle with circumference 5m?
Radius of circle: 5/2*pi m
What is the circumference of a circle with a radius of 5 yards?
The circumference is Pi x Diameter. The radius is half the diameter. So the circumference is also 2 x Pi x Radius. Pi= 3.14159 Radius is given as 5 yards. So the circumference is 31.459 yards or 94.377 feet or 1132.5 inches.
What is the volume if the radius is 3 and the height is 5?
Well, isn't that just lovely! To find the volume of a cylinder, we use the formula V = πr^2h. So, with a radius of 3 and a height of 5, we can plug those values in to find the volume. Just remember to square the radius, multiply by the height, and you'll have your answer in no time!
