If ten inches is the diameter, the circumference is 31.4159 inches.
A circle that is ten feet in diameter has a circumference of (approximately) 31.4 feet.
10 x pi ie 3550/113 = 31.416"
1.9 and the diameter is ten
The circumference of a circle if the diameter is 10 feet long is: Pi x 10 (about 31.416).
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.
Circumference = pi * diameter = 3.14159 * 11.6 = 36.44 Rounded to the nearest ten, that is 40 units.
Circumference=Diameter*pi so plug in 10 = Diameter * pi and solve. I hope you can do this by your self from here
The area is 78.5 square inches.
Use the equation for circumference: C = pi * d Plug in 10 inches for "d" => C = 3.14 * 10 inches = 31.4 inches 31.4 inches is the circumference of a dinner plate with a diameter of 10 inches. Key: C = circumference d = diameter pi = 3.14
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.
Area = pi R2 = 25 pi = 78.54 square inches (rounded)
