What is the tangential speed of an object moving in a circle with a radius of 5 that is going around 3 times in 4 seconds?
I suggest you calculate the total distance travelled (use the formula for the circumference of a circle), then divide this result by the time to get the speed.
What is the circumference of the center circle on a soccer field?
The circumference of the center circle of a soccer field is pi times its diameter (which is 10 yards). It could also be expressed as 2 times pi times its radius (which is 5 yards). It's about 31.416 yards.
How did the Romans work out the area of a circle?
The area of a circle is the number of square units inside that circle, if each square in the circle to the left has an area of 1cm2, you could count the total number of squares to get the area of this circle. However, it is easier to use one the following formulas; A=.r²or A=pi times r times r, where A is the area and r is the radius.
