288
you have to add the 4 sides together 50 + 50 + 94 + 94=288
It is either the Second or third one
Answer:
the answers are A B AND D
Step-by-step explanation:
To find perpendicular lines you take the slope and change the sign and find the reciprocal. after doing that you set it up as a new equation that you will use to find b using the point.
in this case
y= - 2/5x +b
plug in the x and y values of the point (5, -4) to find b
b= -2
you put that together to get the equation
Answer:
35 cm
Step-by-step explanation:
The volume of a cylinder is given by ...
V = πr²h
We want to find h for the given volume and diameter. First, we must convert the given values to compatible units.
1 L = 1000 cm³, so 99 L = 99,000 cm³
60 cm diameter = 2 × 30 cm radius
So, we have ...
99,000 cm³ = π(30 cm)²h
99,000/(900π) cm = h ≈ 35.01 cm
The oil is 35 cm deep in the drum.
