The surface area of a cylinder is define by the formula S.A.=2πrh+2<span>πr^2, where the first part of the formula refers to the lateral area, perimeter, or circumference and the second part to the area of the bases, which are circles.
On this exercise it is asked to find the lateral area of a cylinder whose radius is 6 cm, and has a height of 20cm. To find the lateral area of the cylinder you should substitute this values into the formula, S.A.=2</span>πrh, and as can be seen the answers are given in terms of <span>π or pi.
S.A.=2</span><span>πrh
S.A.=2</span><span>π(6cm)(20cm)
S.A.=2</span><span>π(120cm)
S.A.=240</span>π cm^2
The lateral area of the cylinder is 240<span>π cm^2 or in other words letter B from the given choices.</span>
Hello!
Answer:
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
<em>First, you switch sides. *Group like terms*</em>
<em>Then, you add the similar to elements. You can also add the numbers from left to right.</em>
, is the correct answer.
Hope this helps!
Have a nice day! :)
The four answer choices are equal and pass through the point (-3,1), which you verify replacing the variables:
y - 1 = (x + 3)
1 - 1 = -3 + 3
0 = 0.
The other factor that you have to considerate is the slope.
The slope of the equation y - 1 = x + 3 is 1 (the coefficient of the x).
Given that the slopes of two parallel line are the same (equal), you need to determine the slope of the parallel line.
Once you know the slope of the parallel line, you can choose the right option.
The equation shown, y - 1 = x + 3 is the right fit if and only if the parallel line has slope 1.

Answer:
18x-16
Step-by-step explanation:
expression: (11x-8)+7(x-1)
ok so what you want to do is combine like terms
but first you are going to distribute
(11x-8)+(7x-8) you distribute the 7
they you can subtract 8 from -8 and that will give you -16
you will then add 11x and 7x which will get you 18x
the final expression will be 18x-16
