Completing the squares, the correct statements regarding the equation of the circle are given by:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center and radius r is given by:
In this problem, the equation is given by:
x² + y² - 2x - 8 = 0.
Completing the squares:
(x - 1)² + y² = 8 + 1²
(x - 1)² + y² = 9.
Hence the center is (1,0), the radius is 3, and the correct statements are:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Answer:
36π cm cubed
Step-by-step explanation:
Surface area of a cylinder is 2πr^2 + 2πrh
4 cm is the diameter in the image, so the radius is 2 (4/2)
7 is the height
π2(2^2) + π2(2)(7)
8π + 28π
36π
Answer:
Step-by-step explanation:
Only j,q,k beat 10 and there are four each of them so there are 12 cards that will beat the ten. 4 cards have already been drawn so there are 52-4=48 cards left in the deck, so the probability of beating the 10s is
12/48
1/4
Which is 25%
Choose any x,y pairs from the table and calculate the slope.
