Answer: 21.994 cm²
Step-by-step explanation:
Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.
Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142
Now area of the bigger circle = 3.142 x 3²
= 3.142 x 9
= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2
= 6.284 cm².
Therefore are of the shaded region = 28.278 - 6.284
= 21.994 cm²
Let's move all to one side:
6r+7-13-7r=0
and re-arrange to have similar terms together:
6r-7r +7-13=0
let's add up what we can:
-1r-6=0
we can move the -6 to the other side and multiply both sides by -1 and we get:
r=-6 This is the<em> solution. </em>
