Given:
- Height of cylinder is 18.2 cm
- Radius of cylinder is 3 cm
To Find?
Solution:
Using formula:
- Surface area of cylinder = 2πr (h + r)
Substituting values in the formula:
- Hence, (B) 399.4 cm² is right answer.
Answer: A, x = 24 degrees.
Step-by-step explanation: If Angle 1 and Angle 3 are vertical angles, that means that they are congruent. Thus, you would structure the equation 3x + 72 = 6x.
Solution:
3x + 72 = 6x
72 = 3x
x = 72/3
x = 24
We have to a for its value 6, then multiply by its coefficient to then subtract.
<h2>Therefore, the expression is equivalent to 44.</h2>
y=3x+6
Use
y=mx+b
to calculate the equation of the line, where
m
represents the slope and
b
represents the y-intercept.
Slope is equal to the change in
y
over the change in
x
, or rise over run.
