PI x r^2 is the equation for the area of a circle. Clearly, we have 3 quarters of a circle here, so we can divide our answer by 4 and then multiply it by 3.

PI x 10^3 = 314.159...

Divide by 4 = 78.540...

Multiply by 3 = 235.619...

Therefore the answer is the third one.

If the sum of six consecutive even integers is 306, what is the smallest of the six integers

Neko [114]

306/6 is 51 is you add one to one side and take away the other the six numbers become: 46, 48, 50, 52, 54, 56 as you added one to one side substituting the other you took away from, therefore the smallest would be 46.
