Evaluate the series shown. then write an equivalent series using summation notation such that the lower index starts at 0. ∑^3 n=1 2(n+5) fast

Sample Response: Substitute the values 1, 2, and 3 into the expression 2(n + 5), then find the sum. The summation is equal to 12 + 14 + 16 = 42. You can rewrite the summation as the sum of 2(n + 6) from 0 to 2.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

the answer is 62.8 cubic units
