Volume of cone= 1/3 πr²*h
15²=10²+h²
h²=15²-10²=125
h=√125
Volume of cone= 1/3 *π*100*√125=π/3*(100*5√5)=500π√5/3
Volume of sphere=4/3*π*r³=4/3*π*1000=4000π/3
Volume of half sphere=(4000π/3)/2=2000π/3
All Volume=500π√5/3+2000π/3
250 - 5(x) = 50
250 (-250) - 5x = 50 (-250)
-5x = -200
-5x/-5 = -200/-5
x = 40
hope this helps

Answer:
B
Step-by-step explanation:
Dean recorded the results of spinning the spinner 60 times:
- Number 1 spun 12 times
- Number 2 spun 17 times
- Number 3 spun 15 times
- Number 4 spun 16 times
The <u>experimental probability</u> is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
Find all experimental probabilities:

Hence, option B is correct
