Best ResponseYou've already chosen the best response.1You can find the ratio of the shaded to unshaded. So we have: 240 degrees of the thing is UNSHADED right? So this means that 120 degrees IS shaded. This means that 120/360=1/3. So the shaded region is 1/3 of the total region. So we need the area of the total region. We have a radius of 2 cm. This gives: 4 pi cm^2 for the TOTAL area, Multiply by 1/3 to get the area of the shaded region. so: 4/3 pi cm^2. :)
