How do you show your work to go with how to find the circumference of a circle if the radius is 5?

Circumference = 2*pi*radius In this case radius = 5 units so circumference = 31.4159 units approx.


What is the radius of a circle with the circumference of 13 ft show steps please?

2*pi*radius = circumference 2*pi*radius = 13 Making the radius the subject of the formula is: radius = 13/(2*pi) = 2.06901426 feet Check: 2*pi*2.06901426 = 13 feet


If a circle has a circumference is 5pi millimeters how do you find the area of the circle show your work also i do not have the radius or any other info?

Circumfernce = 5*pithat is, circumference = pi*d = 5*pi where d is the diameter.Therefore, circumference = 5 millimetres and so radius = d/2 = 2.5 mm.Now that the radius is known, area = pi*r^2 = 19.6 mm^2.


What is the radius of a circle with a circumference of ten point nine nine meters Use three point one four for pi and show your work?

radius = circumference divided by 2 x pi so 10.99/6.28 = 1.75 metres


How do you find the circumference of a circle from the radius?

Square the radius and multiply the result by 3.14. You may want additional digits of pi for greater precision, but that's the basic idea.The formula is πr² (that's "pi r squared," if the character doesn't show up properly).ANSWER:The above answer is wrong! The above gives the area of a circle, not the circumference. Besides pie are round, cornbread are square. Pi = 3.1416 as stated above.The circumference of a circle is 2 times the radius times pi .This is because pi for all circles is the circumference divided by the diameter. So, pi times the diameter equals the circumference. The diameter is twice the radius.


How do you work out the circumference of a circle using radius?

The formula for calculating the circumference of a circle is 2πr, where r is the radius of the circle and π is 3.1415926535890793 - usually shorted to either 3.1416 or 3.14 So that the circumference of a circle with a radius of 10 units is 62.83 units There are pi radians in a half of a circle. Thus, the measure of a central angle which is a straight line is pi radians. We have a formula that show that the length of an intercepted arc is equal to the product of the angle in radians that intercepts that arc, with the length of the radius of the circle. So we can say that the length of a semicircle is (pi)(r). In a full circle are 2pi radians. So the length of intercepted arc from a central angle with measure 2pi is 2(pi)(r).


Can you show me a written answerfrom top to bottom on how to find the diameter radius and circumference and area of a circle of 3.14 is the diameter?

diameter: you have stated that it is 3.14 radius: half the diameter, therefore 1.57 circumference: pi times the diameter, therefore 3.14 x 3.14 = 9.86 area: pi times the radius squared, therefore 3.14 x 2.46 = 7.72


How do you show flow chart for calculating area of circle?

Area of any circle is: pi*radius*radius or pi*r^2


What does a radius in a circle looks like show picture?

It is the line from any point on a circle to the center


What is the area of a circle with the radius of 4 in to the nearest tenth show work?

Area of a circle = (pi) x (radius)2 = (pi) x (4)2 = 16 pi = 50.3 in2 (rounded)


How can you calculate the area of a circle with a radius of 1.4m Please show your method of doing so?

Area of circle = pi*r2 where r is the radius. Area = pi*1.42 = 6.16 m2 (to 2 dp)


How do you divide a circle into thirds?

Assuming you know the location of the center of the circle, to divide a circle into thirds, do the following:mark a point on the circumference and, using a protractor, mark 120 degreesthen repeat for the final markA line from the mark on the circumference to the center will show an angle of 120 degrees.
