A circular spinner for a game has a radius of 10 cm. The probability of winning on one spin of this spinner is 2/5. What is the area, in sq cm, of the WIN sector? Express your answer in terms of pi.
nvm, i got the answer, it was 40
That answer makes sense. The total area of a circle is pi * radius^2, the area of the total spinner is 100pi.
2/5 of this is success, so the answer is 2/5 * 100pi = 40 pi
