Answer:
11309.7 cm
Step-by-step explanation:
Volume = πr^2h
= π×20^2×9
= 3600π
= 11309.733552923
=11309.7 cm
First, we must find the unit rate in other words, we must find how much miles the car travels in 1 hour or vice-versa.
Now, plug in the ten instead of a 1 in the proportion of,
This is simply because 1*10=10 and 43*10=430.
I hope this helps!!
<h3>Answer : </h3>
SSS congruency criteria can be used here to prove ∆ABC ≅ ∆DCB
<h3>Solution : </h3>
In ∆ABC and ∆DCB
AB = CD (given)
AC = BD (given)
BC = BC (common)
So, by SSS congruency criteria,
∆ABC ≅ ∆DCB
For the two circles x is equal to the radius, for the first circle we have x = 9 units and for the second one we have x = 11 units.
<h3>
How to find the length of the segments?</h3>
Define how circles are defined. A circle is the set of all points on a plane that is equidistant to a given point, which we call the center of the circle.
That constant distance is called the radius, so the distance between the center of the circle and any point on the circumference is constant.
Now, let's look at the first circle, here you can see that the lenght "x" connects the center with the circumference, this, x is equal to the radius. And the other segment also does that and it measures 9 units, then we can conclude:
x = 9
For the other triangle we have exactly the same situation, here x also represents the radius, and this time we can see that the radius measures 11 units, then:
x = 11 units.
