radius = 11 cm
Area of a circle in square cm = pi*radius squared
16.328 cm squared.
56 cm squared
The radius of a circle is half of its diameter. If you have a diameter of 12.7 cm, the radius would be 12.7 cm divided by 2, which equals 6.35 cm. Therefore, the radius is 6.35 cm.
The radius of a circle is half of its diameter. If the diameter is 18 cm, then the radius would be 18 cm divided by 2, which equals 9 cm. Thus, the radius is 9 cm.
Since area equals Pi times radius squared take and substitute what is known. 345 equals Pi times the radius squared. divide Pi into both sides for 109.8 equals the radius squared. Now take the square root of 109.8 to get an r of 10.47936 cm.
Area of a circle in square cm = pi*radius squared
1.63 cm
The answer is 254.469005cm squared
16.328 cm squared.
56 cm squared
9474.76 cm squared 3730.22 in squared
The radius of a circle is half of its diameter. If you have a diameter of 12.7 cm, the radius would be 12.7 cm divided by 2, which equals 6.35 cm. Therefore, the radius is 6.35 cm.
if a radius is 5cm the diameter is 10cm rule- you double the radius
630 cm squared equals 97.65 inches square.
60cm
The circumference = 18.8 cm
