A circle that is ten feet in diameter has a circumference of (approximately) 31.4 feet.
20 cm
The area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches is: 25 square units.
The two equations you must know to solve this are The circumstance of a circle is the value of pi times the diameter c=pi*d -and- The radius of a circle is halve the diameter r=.5d or d=2r If we plug in 62.8 for c, 2r for d and 3.14 for pi, the equation becomes 62.8=3.14*2r Divide by 3.14 20=2r Divide by 2 10=r the radius is ten meters
1.9 and the diameter is ten
The circumference of a circle is pi x diameter, where pi equals approximately 3.14. Therefore, the inner circumference of a brick circle with an inside diameter of 10.5 feet is 32.99 feet. As a result, 33 one foot bricks would create a circle with a diameter slightly larger than 10.5 feet, without any gaps between the bricks.
If ten inches is the diameter, the circumference is 31.4159 inches.
78.5398163 meters.
Calculations when converted to SI system of units. 10 feet = 3.048 meters Formula is S=Pi*R^2 Pi~= 3.14 Ambiguous - ten feet is diameter, radius or length of a circle? if it's 10 feet radius, then S=3.14*3.048^2=29.1715546 sq meters or 314 square feet Assuming it is diameter, radius is would be half of it - 5 feet or 1.524 meter. S=3.14*1.524^2=7.29288864 sq meters or 78.5 square feet If it is the length of circle, the formula to get the radius is r=c/2Pi=3.048/(2*3.14)=0.485350318 meters or 1.59235669 feet Area then is S=3.14*0.485350318^2=0.739673884 sq meters or 7.96178342 sq feet
