Answer:
h=31.4 cm
Step-by-step explanation:
A=lateral surface area
c=circumference
h=height
A= c*h
solving for h we get:
h=A/c=120pi/12=10pi
Answer:
1/4
Step-by-step explanation:
A P E X
Let
be the line that passes through both points.
We know that
and
. So:

Solving the system, we get that a= -1 and b = 6.
So the line is equal to
.
Answer:
B. y= 1/2 x - 3
Step-by-step explanation:
base equation: y= mx+ b
slope(m) equation:
y2= -1 y1= -3
x2= 4 x1= 0

y- intercept: -3
found by taking the y from (0,-3)
M is a midpoint of BC so:

Length of MA:
