Answer:
result = 15cm
Step-by-step explanation:
Hi! to can solve this, we have to keep in mind this formulas:
<h3>1) Area of a circuference: </h3><h3 />
A1 = π ; where r = radius
<h3>2) Area of a cylinder:</h3><h3 />
A2 = (π ) * (h) ; where h= height
now we solve:
first, we have to calculate the area of the circumference
A1 = =
then, we already know the volume of the cylinder, and the area of the circumference, so we have to find just h of the second formula:
A2 = (π ) * (h)
<h3>
=
* (h)</h3><h3 /><h3>
= h</h3><h3 />
h = 15cm
Answer:
D.
Step-by-step explanation:
To write the equation of a circle, use the formula where the center of the circle is (h, k).
This means the equation is .
Find the radius r by finding the distance between (3,2) and (-6,-4) using the distance formula.
Since the radius is √117 and therefore .
The equation is .
Pythagorean Theorem can be used only for right triangles.
(leg1)² +(leg2)² = hypotenuse ²
So, answer is the right triangle B.
It is given that the measurement of arc AC = 155 . And AB is the diameter, so measurement of arc AB=180 degree . Therefore arc BC = arc AB - arc AC = 180-155=25 . And the radius divides chord CD in two equal parts, so it divides the arc too in two equal parts. Therefore if the measurement of arc CB =25 , then the measurement of arc BD =25 too. Hence x =25 .
