You measure the pie's diameter (length through the middle), and divide it in half.
radius = 1, C=2(pie)r
Circumference = 2 x pie x radius Therefore, radius = 10/2/pie =1.6
The radius is 18.
you have to use the formula : C= 2* radius* Pie symbol. * IS MULTIPLYING. Pie always equals to 3.14, so suppose the radius is 5. You would multiply 5*2*3.14. Your answer would be 31.4.The reason you have to multiply the radius by 2 is because you have to make the radius turn into the diameter which is double the radius to make the equation simpler. Always remember to use pie as 3.14.
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
radius = 1, C=2(pie)r
pie times radius squared
Circumference = 2 x pie x radius Therefore, radius = 10/2/pie =1.6
since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie
The radius is the circumference divided by pie, all divided by two. :)
The radius is 18.
Let C be the circumference, r be the radius, and (pie)= 3.141592654 C = 2 x (pie)x r r = C ÷ (2 x (pie))
The pie plate with the 5-inch diameter is greater.
The formula for radius of a cone is radius is equals to square root of volume times 3, which is divided by height times pie. Pie refers to 22 divided by 7.
Pie radius square
pie multiplied by the radius.
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
