How many feet of rope does it take to make to make a 15 ft circle?
Assuming the 15 feet is the diameter of the circle. Formula to find the circumference of the circle is pi x diameter. 15 × 3.14 = 47.1 feet So the rope will be 47.1 feet long.
A circle has a circumference of 94.2 centimeters Its diameter is 15 centimeters which expression can you use to find the approximate value for pi?
You've stated an impossible question. If a circle has a circumference of 94.2 cm, it has a diameter of 30 cm. If it has a diameter of 15cm, it has a circumference of 47.1 cm.circumference = 2 * pi * radius = pi * diameterIf you had stated the question correctly (changed circumference to 47.1 cm OR changed diameter to 30 cm OR changed "diameter" to "radius"), then the answer would be:pi = circumference / diameter = (e.g.) 94.2 cm / 30 cm
What is the circumference of a circle if the diameter is 15 cm rounded to the nearest tenths place?
Assume pi is 3.14 Therefore: Circumference = 3.14 x 15dia = 47.1cm
What is the radius of a circle with a diameter of 15 cm?
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
If the radius is 15 cm what is the circumference?
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
