Answer:
You divide 2 by 3, then multiply by x, to get -12
Answer:
A. ¹/27
Step-by-step explanation:
✔️Volume of large sphere = ⁴/3πr³
r = 18.6 in.
Volume of large square = ⁴/3*π*18.6³ = 26954.26 in.³
✔️Volume of small sphere = ⁴/3πr³
r = 6.2 in.
Volume of small sphere = ⁴/3*π*6.2³ = 998.31 in.³
✔️Ratio of the volume of the smaller sphere to the larger sphere = 998.31 : 26954.26
= 1 : 27
Therefore, the volume of the large sphere is ¹/27 of the volume of the small sphere.
We have been given image of circle that passes through point . We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point .
Now we will use equation of circle to find radius.
, where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point and coordinates of center and solve for r as:
Switch sides:
Now we will take positive square root on both sides:
Therefore, radius of circle will be and center is at point .
