Find the volume and round to the nearest tenth as needed

monitta

Answer: 1962.4 cubic mm

Step-by-step explanation:

The volume of the larger cone is $V=\frac{1}{3}(\pi)(10^{2})(20)=\frac{2000\pi}{3}$

The volume of the smaller cone is $V=\frac{1}{3}(\pi)(3^{2})(14)=42\pi$ .

So, the volume is $\frac{2000\pi}{3}-42\pi \approx \boxed{1962.4}$

Please help in the question it should be if t=-6 when r =-2 its an error

Natasha2012 [34]

Answer:

r = - $\frac{12}{7}$

Step-by-step explanation:

Given that r varies inversely as t , then the equation relating them is

r = $\frac{k}{t}$ ← k is the constant of variation

To find k use the condition t = - 6 when r = - 2, then

- 2 = $\frac{k}{-6}$ ( multiply both sides by - 6 )

12 = k, thus

r = $\frac{12}{t}$ ← equation of variation

when t = - 7, then

r = $\frac{12}{-7}$ = - $\frac{12}{7}$

Answer:

Step-by-step explanation:

+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5

−(−) 6−(−3) = 6 + 3 = 9

+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5

−(+) 8−(+2) = 8 − 2 = 6
