Answer:
14 inches
Step-by-step explanation:
Using this information, we can form an equation.
Since there are 3 sides in a triangle, and each side increased by 6, that means that the perimeter increased by 18 inches. Down below, I did 3x because there are 3 sides in a triangle.
(This is the equation you'd want to do to get the answer)
3x + 3 * 6 = 60
Simplify:
3x + 18 = 60
Same to both sides
3x = 42
Isolate x:
x = 14

Answer:
103.62 cm squared :)
Step-by-step explanation:
To solve this problem, lets start with the grey area only and essentially we want to treat it like it's own circle. So the formula for circular area is A=pi times r²
so for the radius of the grey region, we will simply add 3 and 4 cm.
3+4=7cm
Then we can plug that into the area equation, which is:
A = (3.14)(7²)
Solve for that and we should get 153.86 cm²
We'll hold onto that for now while we solve for the white circle next:
A = (3.14) (4²)
A = 50.24cm²
Lastly, let's bring back the grey area we found earlier, and subtract the white area from it:
153.86 - 50.24 = 103.62 cm²
hope this helps and good luck~
