Answer:
The answer is (x,y)=(-10,-7)
Step-by-step explanation:
- The solution comes from replace x= -10 into the equation of y=2/5 x -3.
- Replacement of x= -10 into y = 2/5 x -3 results:
.
V=hpir^2
tricky, they didn't give us radius
they just gave circiufmerece
c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r

v=hpir^2
v=66pi4^2
v=66pi16
v=1056pi
v=3315.84 cubic inches
