1200 ÷ 3 = 400 ⇒ 400 × 3= 1200 so the answer is right :))
i hope this be helpful
have a nice day
904.32 is the volume.
Volume of sphere
= (4/3)πr³
= (4/3) × 3.14 × (6cm)³
= (4/3) × 3.14 × 6cm × 6cm × 6cm
= 4 × 3.14 × 2cm × 6cm × 6cm
= 904.32 cm³
The answer of square root of -121 is 11
Answer:
(x + 1)^2 + (y - 1)^2 = 74
Step-by-step explanation:
By looking at the graph, we can see the center of the circle is (-1, 1).
Next, we can find the radius. We are given the point (6, -4) is on the circle. The distance from the center to a point on a circle is the radius. We can plug the points (-1, 1) and (6, -4) into the distance formula to get the radius:
r = √([-1-6]^2 + [1-(-4)]^2)
r = √(49 + 25)
r = √74
The equation of a circle is denoted in the form:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can plug in the values we calculated:
(x + 1)^2 + (y - 1)^2 = 74
