Unsure what you mean by diagonal right triangle
but if you wanted to find the hypothenuse (longest side) of a right triangle, you can apply pythagorean theorem

where c is the hypothenuse
a and b are the other sides
1. We know that 30% expressed as a decimal is 0.30
Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.
Therefore 960 people were using the internet out of the 3200 surveyed.
Answer:
The rate rate of change of radius is
inches per second when the diameter is 12 inches.
The radius is changing more rapidly when the diameter is 12 inches.
Step-by-step explanation:
Consider the provided information.
A spherical balloon is being inflated at a rate of 3 cubic inches per second.
The volume of sphere is 
Differentiate the above formula with respect to time.

Substitute the respective values in the above formula,


The rate rate of change of radius is
inches per second when the diameter is 12 inches.
When d=16


Thus, the radius is changing more rapidly when the diameter is 12 inches.
