Of segments and , which of the segments has a greater area based on the given information? justify with your work. circle has ra
WITCHER [35]

Of segments and, which of the segments has a greater area based on the given information circle has a radius 12m has the greater base.

<h3>What is the area of base?</h3>

Substitute the fee of "r" into the equation for the place of a circle: place = πr^2. Note that π is the image for pi, which is about three.14. For example, a circle with a radius of three cm could yield an equation like this: place = π3^2.

  1. Once you discover the place of the world, all you need to do is get the place of the triangle after which subtract the place of the triangle from the world and to be able to let you know the place of CFD and CED and can help you realize which one is more.
  2. For instance, Lets discover A, area place = 90/360 x πx10 ^ 2 = 25pi
  3. Now we could get the place of the triangle, that is place triangle = 1/2x bh xsin C
  4. Now we could discover B of the triangle, that is place angle = 1/2x bhx sin place triangle = 1/2 x 12 x12sin 60 = 36 sqrt ( three CFD=sec place - place of gle = 24 pi-36 sqrt three)=13.04m^ .
  5. So A has the more area base.
