The answer would most likely be C
Answer:
22
Step-by-step explanation:
3.56 = 4
5.9 = 6
12.087 = 12
4+6+12 = 22
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
Answer:
x = 30
Step-by-step explanation:
Since this is a right triangle,
90 = (x + 20) + (x + 10)
90 = x + x + 20 + 10
90 = 2x + 30
90 - 30 = 2x
60 = 2x
60/2 = 2x/2
30 = x
Check:
x + 20
30 + 20 = 50
x + 10
30 + 10 = 40
50 + 40 = 90
Hope this helps!
Step-by-step explanation:
Given that,
- Length = 6y + 10
- Width = y – 3

Therefore, perimeter is (14y + 14) units.
