Answer:
The radius of sphere with volume 4500 cubic inches is 10.24 inches.
Step-by-step explanation:
Let V be the volume of the sphere
Given
Volume of sphere = V = 4500 cubic inches
Let r be the radius of the sphere
The volume of the sphere is given by the formula

Putting the known values

Taking cube root on both sides
![\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%20%3D%20%5Csqrt%5B3%5D%7B1073.8636%7D%20%5C%5Cr%20%3D%2010.2403)
Rounding off to nearest hundredth
The radius is: 10.24 inches.
Hence,
The radius of sphere with volume 4500 cubic inches is 10.24 inches.
Using the slope concept, considering it's value of 0.3415, it is found that the angle of elevation is of 18.86º.
<h3>What is a slope?</h3>
The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
Hence, we have that:

Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:

where it has taken into account the sum of the area of a square and four triangles:

h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:

hence, the surface area is 85cm^2
