You have to convert cm to m or m to cm (all if them need to have the same unit)
50cm= 0.5m
20cm= 0.2m
l=3+0.5= 3.5m
b=2+0.2= 2.2m
A=(3.5)(2.2)= 7.7m^2
The y-intercept is -2 and the slope is 2/3

Answer:
y = -x - 11
Step-by-step explanation:
We know the equation must be: y = -x + c
However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.
So:
-1 = -(-10) + c
-1 = 10 + c
so c = -11
So our equation is:
y = -x - 11
Answer:
inches or approximately 5.97 inches
Step-by-step explanation:
Use the cone volume formula: V =
r²
The diameter is 8 inches, so the radius will be 4 inches.
Plug in the radius and volume, and solve for h
V =
r²
100 =
(4²)(
)
100 = 16

Divide each side by 16
= 
Cross multiply and solve for h:
4
h = 75
h = 
So, the cone's height is
or approximately 5.97 inches
