Step-by-step explanation:
The radius of circles is 7cm,24cm
Area of smaller circle is πr
2
⟹π×7
2
⟹49π
Area of Larger circle is πr
2
⟹π×24
2
⟹576π
Area of required circle ⟹576π+49π
⟹625π
Radius of circle is given by
625

Answer:
(5,-3) if the system is
y=x-8
2x+3y=1
Step-by-step explanation:
I think the system is to read:
y=x-8
2x+3y=1.
Please correct me if I'm wrong.
I'm going to plug 1st equation into 2nd equation giving me:
2x+3(x-8)=1 ->I replaced y with (x-8).
Distribute:
2x+3x-24=1
Combine like terms:
5x-24=1
Add 24 on both sides:
5x=25
Divide both sides by 5:
x=5
If y=x-8 and x=5, then y=5-8=-3.
The solution is (5,-3).
