Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.
1 answer:
Answer:
113.1 unit²
Step-by-step explanation:
A cylinder is a shape with two round ends and two parallel lines connecting the round ends.
Height=9 unit, Base=4 unit
The lateral surface area of a cylinder (A) is given by the equation:
where r is the radius of the cylinder and h is the height of the cylinder.
Given that the base = 4 unit, therefore the diameter (d) = base = 4 unit. Also the height (h) = 9 unit.
Radius (r) = d/2 = 4/2 = 2 unit
Calculating the area of the cylinder is as follows
The area of the cylinder is 113.1 unit²

Answer:
Step-by-step explanation:
Given:
Required:
Solve for y (make y the subject of the formula)
SOLUTION:
Square both sides
Subtract both sides by x
Divide both sides by 2
Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2
and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 =
<- equation1
Area of square = Side* Side= x*x =
<- equation2
As per given data, Equation1 and equation 2 are equal
so
= tex] x^{2} [/tex]
x = 5
So the side of square = 5 units
For Square, both dimensions are equal.
