Answer:
The center of the circle is (2/3, 0) and radius is ±6units
Step-by-step explanation:
Given the equation of a circle given as shown;
(x-2/3)²+y² = 36
To get the radius and centre of the circle, we will compare the equation with the general equation of a circle given as;
(x-a)²+(y-b)² = r² where (a, b) is the centre of the circle and r is the radius.
Comparing with the given equation,
we will see that;
a = 2/3, b = 0 and r² = 36
If r² = 36
r = ±√36
r = ±6
This shows that the center of the circle (a, b) = (2/3, 0) and radius is ±6
Answer:
it will take 7 nights
Step-by-step explanation:
Answer:
Given:
Radius of large sphere: R1
Volume of sphere: V1
Radius of small sphere: R2
Volume of sphere: V2
R1=2R2
We know that:
Volume of a sphere: 4/3πR^3
Volume of large sphere: 4/3πR1^3
Now we know that R1=2R2(given)
Thus volume of large sphere(V1) 32/3πR2^3.
Volume of small sphere(V2): 4/3πR2^3.
Ratio of volume of large sphere to small sphere is 8:1.
