As you were copying the question, did you notice the drawing alongside it ?
Well, see, that sketch is actually part of the question; anybody who wants to
try and answer it needs to see that drawing.
About 4.712 inches.
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
It is very easy math!
The diameter is 15 ft, so your radius would be 7.5 ft.Now you can split the circle into fourths knowing each radius is 7.5 ft.Then use the formula S=rθ to find the arc length. Since it's split into fourths, you know each angle is 90o.So then plug it in.S=(7.5)(90o)Multiply 90o times pi/180o to get rid of the degrees.So then you haveS=(7.5)(pi/2)Plug it into your calculator.Multiply your answer by four (since we split it into fourths, we only found the arc length for one fourth of it).And your answer should be 47.12 ft.
the side length is 15 inches.side length:= cube root of 3375 in3= 15check:volume of cube = s3 = 153 or 15 *15*15 = 3375
15 in
The total circumference of the circle is (2 pi R) = 30 pi.The central angle of 90° is 90/360 = 1/4 of the circle.The minor arc = 30 pi/4 = 23.562 (rounded)

diameter = 15pi/pi = 15 units in length
The circumference of 15 is: 47.12
I thInk it's to do with your height if you are tall your arms will be a bit longer I THINK
A circumference of 47.1'
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
A circle with a radius of 15 inches has a circumference of: 94.2 inches.
About 4.712 inches.
The circumference is 47.1 feet.
1 It's a perfectly 2 dimensional geometrical shape 2 It can be easily constructed with a compass 3 Its perimeter is better known as its circumference 4 Its diameter spans its circumference cutting through its centre 5 Its radius is half of its diameter 6 It can be concentric with other circles sharing the same centre 7 Its circumference divided by its diameter is the value of pi 8 Its pi value has never been determined because pi is an irrational number 9 Its circumference length is: 2*pi*radius or diameter*pi 10 Its area is: pi*radius squared 11 Its radius can be found by: circumference/2*pi 12 Its diameter can be found by: circumference/pi 13 Its circumference touches a straight line tangent at only one point 14 Its circumference is a full revolution of 360 degrees 15 Its circumference measured in parts are arcs 16 Its radius is the length of a radian arc 17 Its radian arc is just under 57,3 degrees 18 Its lines of symmetry are infinite 19 It has chords which are straight line spanning its circumference 20 It has sectors which is an area enclosed by an arc and 2 radii 21 It has segments which is an area enclosed by a chord and an arc 22 It has certain particular interior and exterior angular properties 23 Its best friend is the sphere because they have so much in common 24 It linked together with other circles form the Olympic sport's emblem 25 Its properties have been known since pre-historical times and even beyond the construction of Stonehenge which relies on the circle for its mysterious annual geometrical truthfulness
