Circumference = 2 x pie x radius Therefore, radius = 10/2/pie =1.6
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
A = 25 pi so R = 5, making C = 10 pi ie 31.415 m
circumference = diamiter times pie 3.14 times 10 move the decimal over once its 31.4
If a circle's diameter is 10, the circumference is: 31.416
This circle's area would be 78.54 units squared.
Circumference = 2 x pie x radius Therefore, radius = 10/2/pie =1.6
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
10 x 3.14 (pie) = 31.4
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
all you have to do is take the number 10 and mulitply it by pie which is 3.14 which gives you the answer as 3.140
A = 25 pi so R = 5, making C = 10 pi ie 31.415 m
circumference = diamiter times pie 3.14 times 10 move the decimal over once its 31.4
We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.
If a circle's diameter is 10, the circumference is: 31.416
Area = 78.54 cm2Circumference = 31.42 cm
62.8The square root of 100 is 10.The circumference of a circle is 2(pi)r = 2 x 3.14 x 10 =6.28 x 10 = 62.8
