Answer: 1 and 1/100
Step-by-step explanation: using the place value chart, we can see that 1.01 means 1 unit, 0 tenths, and 1 hundredth. Think of 0 tenths and 1 hundredth as 1 hundredth.So, we have 1 and 1 hundredth which can be written as the mixed number 1 and 1 hundredth or 101/100.
12/7 = 20/x
12x = 140
x = 140/12 = 35/3 = 11.67
so radius of the large cone = 11.67 ft
Volume = 1/3 πr^2h
= 1/3(3.14)(11.67)^2(20)
= 2850.88
Answer is B. 2850.70 ft^3
