Answer is 60.05cm^2


First, find the area of both circular sides:
Area = pi x radius^2
Area = pi x (4.5/2)^2
Area = 15.904....

There are two sides, so times the area of the circle by 2.
15.904... x 2 = 31.808....

Afterwards, find the area of the outside circular part.

You use the formula to find the circumference of the circle as that is just the outside length of the circle.
Circumference = pi x diameter
C = pi x 4.5
C = 4.5pi

Afterwards, times the circumference by the 2cm length.
4.5pi x 2 = 9pi


Then, add up all the area.
31.808 + 9pi = 60.082... approx, where this answer is closest to the last answer.

Why do equivalent ratios form a straight line when<br> graphed? Explain.
irina1246 [14]

Answer:

The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.

Step-by-step explanation:

Equivalent proportions (which are, as a result, equal parts) are two proportions that express a similar connection between numbers. We can make comparable proportions by duplicating or separating both the numerator and denominator of a given proportion by a similar number.

Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.

What is this
allsm [11]

Answer:

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the si…
