Answer: 3054 in^3
Step-by-step explanation: The formula for the volume of a sphere is V = 4/3 pi r^3, where r is radius.
Since the diameter is 18in, the radius would be 1/2 or 9in, and plugged in V is
V = 4/3(3.1415)(9)^3

Answer: OPTION B
Step-by-step explanation:
To solve this problem you must add the areas of each rectangle that form the prism;
The area of a rectangle can be calculated with the formula:

There are three pairs of equal rectangles, then you can find the surface area of 3 rectangles and multiply each one by 2, then you obtain that the surface area of the prism is:

Answer:
Step-by-step explanation:
The above is a right angled triangle
So you take the longest side
9.4^2 - 6.8^2
88.36- 46.24
sqrt of 42.12
6.4899
To the nearest tenth of a degree = 6.56.5ft
