The lateral surface area of the cylinder is option A) 251.3 cm²
<u>Step-by-step explanation:</u>
It is given that,
- The height of a cylinder is 5 centimeters.
- The diameter of the base of the cylinder is 16 centimeters.
<u>To find the radius of the cylinder :</u>
Radius = Diameter / 2
⇒ 16/2
⇒ 8 centimeters.
- The radius of the cylinder is 8 centimeters.
<u>To find the lateral surface area of the cylinder :</u>
The lateral surface area of the cylinder = 2πrh
where,
- π the default value of 3.14
- r is the radius
- h is the height
∴ The lateral surface area of the cylinder = 2×3.14×8×5
⇒ 251.3 cm²
Since the right triangle always has a 90 degree angle they are always similar
Answer:
The first step is to find a number that when subtracted from 2 gives you 2.
Step-by-step explanation:
The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so
first x-2=2, then x-2(+2)=2(+2) which would give us,
x=4
*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.
