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?
Assuming you have a cylinder, the volume is area of the base multiplied by the height. The area of the base is the area of a circle of radius 3 (PI*radius^2 = PI*3^2 = 9*PI). The height is 5. The resulting volume would be 5*9*PI = 45*PI units^3. Did I just do your homework?
