Answer:
1767 cm³
Step-by-step explanation:
We can use volume V = 4/3 π r³
We have diameter of 15 cm. To get radius, we need to divide diameter by 2.
r = 7.5 cm
So now plug in r = 7.5 then calculate V:
V = 4/3 π ( 7.5 )³
V = 4/3 π * 421.875 ≈ 1767.145 ≈ 1767
Hope this helps.
The first question is “32.4”
I’ll come back if I find the other
Answer:
12
Step-by-step explanation:
The sales tax rate would be 8%.
To find how much you spent on tax in the total, you'd begin by subtracting the pre-tax notebook from the after tax notebook.
4.86 - 4.50 = 0.36
So now we know that you spent 36 cents on tax. From there, we'd divide our money spent on tax by our pre-tax total.
0.36 ÷ 4.50 = 0.08
This means that the sales tax is 8%.
Hope I could help!
