Answer:
10 m
Step-by-step explanation:
If the area of a square is 50 m2, then the length of each side will be m, to get the diagonal length, after dividing the square by joining the points of the diagonal with a line, it forms two right angles with length
m each.
the diagonal length represent the hypotenuse side of each of the right angle, knowing the pythagoras theorem:
, so we have:
diagonal = 10 m
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.
