Answer:
volume = 16956 meters
Step-by-step explanation:
volume = area * height
= pi * r^2 * height
= 3.14 * (30m/2)^2 * 27
volume = 16956 meters
Answer:
15.9778
≈ 16
Step-by-step explanation:
Formula= a² + b² = c²
7.7² + 14² = 255.29
√255.29 = 15.9778 or ≈16
Answer:
B
Step-by-step explanation:
The answer is C
P is half of QRS
R is half of SPQ
<span>so angles P and R are complementary.</span>
The general equation of the circle is:
(x -xo)^2 + (y - yo)^2 = r^2
Where xo,yo are the coordinates of the center and r is the radius of the circle.
Here (xo,yo) is (-16,30) and you can find the radius.
You can find the radius using the equation of the distance (Pythagoras) between the center (-16,30) and any point on the circunference. Here use (0,0)
r^2 = (-16 - 0)^2 + (30 - 0)^2 = 1156
Then, the equation is>
(x - (-16) )^2 + (y - 30)^2 = 1156
=> (x + 16)^2 + (y - 30)^2 = 1156. <----- answer
