What is the circumference of 15dm?
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
If a radius is 15 inches long, how long is a diameter?
The radius of a circle is half the diameter, thus your measurement is 30 inches
What is the best estimate of the circumference of a circle if the radius is 15 inches?
Use Circumference = 2 x radius x Pi Pi is 3.14159 appx. Therefore the circumference of your circle is 2 X 15 X 3.14159 inches or 94.25 inches or 7 feet 10 and 1 quarter inches
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
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 with a diameter of 15 inches and a radius of 7.5 inches?
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.
What is the circumference of radius of 15 in?
A circle with a radius of 15 inches has a circumference of: 94.2 inches.
What is the circumference of a circle with diameter 15 inches?
About 4.712 inches.
If the radius of a circle is 15 inches what is the diameter?
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
If a radius is 15 inches long how long is the diameter?
30 inches. The diameter is twice the length of the radius.
What is the circumference if the radius is 15 in?
Circumference = 2*pi*rCircumference = 2*pi(15 inches)= 94 inches========
What is the circumference of 15dm?
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
What is the circumference of a circle that has a diameter of 15 inches?
It is 15 times pi in inches
What is the diameter if the circumference if 15 inches?
15/pi = 4.77"
What is the radius of a circle with circumference of 15 inches?
Radius = 15 / 2 Pi or 2.3873 inches (rounded to 4th decimal).
If the radius of a circle is tripled what happens to the circumference?
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
What is the diameter of a circle if the circumference is 15 inches?
Approx 4.8 inches.
