Answer:
732π cm^3
Step-by-step explanation:
Volume of the biggest cone
(15^2 * π *20)/3 = 1500π cm^3
Volume of the smallest cone
20^3 : 16^3= 1500π : x
x = (1500π * 4096)/8000= 768π cm^3
Volume of the frustum = 1500π - 768π = 732π cm^3
Answer:
203 ; 245
Step-by-step explanation:
158 + 45= 203
question 2
203+42= 245
Answer:
The percent change in runs batted in from 2001 to 2008 is 26.47%
Step-by-step explanation:
The number of runs chipper batted in the year 2001 = 102 runs
The number of runs chipper batted in the year 2008 = 75 runs
Here, so the Change in the runs batted
= Runs Batted in year 2001 - Runs batted in the year 2008
= 102 runs - 75 runs = 27 runs
Now, The percentage change in the run = 
= 
or, The percentage change = 26.47%
Hence, the percent change in runs batted in from 2001 to 2008 is 26.47%
Area of semi circle: you know the radius is 5. 5^2 * pi = 25pi/2 = 12.5pi
For triangle: bh/2 = (10 * 10)/2 = 50
Add them together: 12.5pi + 50
12.5pi = 39.25
39.25 + 50 = 89.25
It’s closest to D
