Find the area of the cross section that is parallel to the base. Round your answer to the nearest tenth.

  21.0

Step-by-step explanation:

The cross section of interest is a triangle whose base is the diameter of the cone, 7 m, and whose height is that of the cone, 6 m. The area is given by ...

  A = (1/2)bh

  A = (1/2)(7 m)(6 m) = 21 m²

In square meters, the area of the cross section is 21.0.

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
