➷ You would use the formula:
volume = 
Substitute in the values:
(note: the radius is half the diameter)
volume = 
Solve:
Volume = 226.1946711
I'm not sure how far you require it rounded, or if you want the whole value so I will just leave the entire value. If you need assistance with rounding it to specific figures, just comment down below and I'll help.

To find the answer just do the opposite-
If you added 10, then you subtract 10.
So 23.69 - 10 = 13.69
If you multiply an number by itself, you are basically doing exponents so do the opposite of exponents which is root square.
So you root square 13.69
Which equals 3.7
So the number is 3.7
A) the growth is 56% per week. The 1.56 is multiplying the weight of the pumpkin now by the 56% to get the total weight after the 56% increase.
B) Replace P with 80 and solve for n:
80 = 25(1.56)^n
Divide each side by 25:
80/25 = 1.56^n / 25
3.2 = 1.56^n
Take the natural logarithm of both sides:
ln(3.2) = ln(1.56^n)
Remove the exponent:
ln(3.2) = n(ln(1.56)
Divide both sides by ln(1.56)
n = ln(3.2) / ln(1.56)
n = 2.6 weeks, round to 3 weeks.
C) Change 1.56 to 1.32 and redo the same calculation from B.
80 = 25(1.32)^n
80/25 = 1.32^n /25
3.2 = 1.32^n
ln(3.2) = ln(1.32^n)
ln(3.2) = n(ln(1.32)
n = ln(3.2) / ln(132)
n = 4.2, round to 4 weeks.
Answer:
its D
Step-by-step explanation:
he is incorrect so that leaves us with b or d. and b is wrong about how much cheaper 60% is.
the 40% one is $75.57
the 60% one is $67.98
60% is about 7 dollars less. so it's D
