Hey , here is the answer to ur question.....!
Given: Radii is in the ratio 3:4
To find : ratio of Surface area of the two distinct spheres
Solution: Surface area of a sphere =4* pi *r^2
=>(3/4)^2=9/16
Therefore , the ratio of the areas of teh two distinct spheres=9:16
Hope this helps u!!!!!!.........
Answer is in the attachment.
note:
make a slight change in question 1;
Answer:
The answer to your question is height = 12 mm
Step-by-step explanation:
Data
l = w = 9 mm
V = 324 mm³
h = ?
Formula
V = 
Solve for h
3V = Ab h
3V / Ab = h or h = 3V / Ab
Find the area of the base
Ab = l x w
= 9 x 9
= 81 mm²
Substitution
h = 
Simplification
h = 
Result
h = 12 mm
Do you mean 90,000?
If so, then move the decimal 4 places to the left to make the number land between 1-10. Then use the number of places as the power of 10. If you are moving the decimal right, then the power will be negative.
9x10^4 is 90,000 in scientific notation.
9x10^-4 is 0.0009 in scientific notation.
I belive,
The experimental probability could be more, the same or less than the theoretical probability of rolling a 1 (which is 1/6).
The larger your sample (i. e., as you go beyond 60 tosses), the closer the two different probabilities are likely to be. (Think: Law of Large Numbers).
