15.7
Pi X 5 = 15.7. Pi is equal to 3.14 then you multiply it by 5.
The area of the plate is equal to pi times the square of the radius. Since the plate has a 10 inch diameter, the radius is 5 inches. Therefore, the area is equal to pi times 25, or about 78. 5 inches.
No; circumference divided by diameter equals pi.
Because 2 times the radius is equal to the diameter of the circle
Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
Pi X 5 = 15.7. Pi is equal to 3.14 then you multiply it by 5.
The area of a circle is equal to pi times the radius squared. So in your case it would be 5 squared, (25) times pi which is equal to ~78.5
pi^2
Since the circumference is equal to the diameter times pi, you need to divide the circumference by pi in this case.
When you multiply 12.8 times pi the exact answer is12.8 Pi, but you can round off the answer to40.192because pi is about equal to 3.14.
3.14 x 3.14 = 9.8596
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
The area of the plate is equal to pi times the square of the radius. Since the plate has a 10 inch diameter, the radius is 5 inches. Therefore, the area is equal to pi times 25, or about 78. 5 inches.
If you mean pi then: 50 times pi is about 157 to the nearest whole number
No; circumference divided by diameter equals pi.
98.596
Because 2 times the radius is equal to the diameter of the circle
