Answer: 
Step-by-step explanation:
Given: The diameter of a large lawn ornament in the shape of a sphere = 16 inches.
Then, the radius of ornament =
inches.
We know that the volume of a sphere is given by :-
, where r is the radius of a sphere.
Now, the volume of the ornament is given by :-

Hence, the approximate volume of the ornament 
Answer:

Step-by-step explanation:
Answer:
38.81cm³
Step-by-step explanation:
Volume of a sphere = 4/3πr³
Diameter is 4.2
radius= 4.2/2 = 2.1 or 21/10
4/3 × 22/7 × 21/10 × 21/10 × 21/10
= 4851/125
= 38.808
≈38.81cm³
Answer:
To the nearest percentage, percent increase is 33%
Step-by-step explanation:
Mathematically;
Percentage increase = (new - old)/old * 100%
new = 48 hours
old = 36 hours
% increase = (48-36)/36 * 100%
12/36 * 100%
1/3 * 100%
= 33.33%
Answer: 
Step-by-step explanation:
Given

We can write it as

Express x in terms of y

Replace y be x to get the inverse

To prove, it is inverse of f(x). 

So, they are inverse of each other.
