Step-by-step explanation:
From the attachment, the question has been answered. However, the explanation is as follows;
Given that
This means that
See attachment (1)
Step 1: Locate point 7 on the x axis
Step 2: Locate point 4 on the y axis
Trace these two points until they intersect.
The point at which they intersect, is the required point (7,4) --See attachment (2)
Sphere
The radius of the sphere is the only unknown variable need to find the volume of a sphere.
Step-by-step explanation:
Sphere is a geometrical three dimensional round figure with every point on its surface equidistant from its center. It is a three dimensional representation of a circle. A line which connects from the center to the surface is called radius of the sphere.The diameter of the sphere is the longest straight line which passes through the center of the sphere.
The volume of sphere is given by:
Volume of sphere(V) =
where V is the volume of the sphere
r is the radius of the sphere
= 3.14
Hence the only unknown variable to find the volume of a sphere is the radius.
