Can some one me with this question.

So the small circles are touching each other and they have a radius of 7 inches. so that means that the big circle will have a radius of 14 inches which is double the small circles radius. after we find the radius of the big circle, we have to calculate the big circles area. which we will find by the formula


14 squared times pi is 615.44
this is the big circles are but the question askes the area left after we subtract the 2 small circles
we find the are of the small circles by doing

which is 153.86.
after finding the area of the small circles we multiply it by two a d subtract it from the big circles area


and we find 307.72 which is the closest to 308
so the answer is D

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
