Find the volume of a right circular cone that has a height of 3.9 ft and a base with a circumference of 16.3 ft. Round your answ
MissTica

Answer:

The answer to your question is Volume = 27.5 ft³

Step-by-step explanation:

Data

Volume = ?

height = 3.9 ft

Circumference = 16.3 ft

Process

1.- Calculate the radius of the Cone

   Circumference = 2πr = 16.3 ft

-Solve for r

                                    r = 16.3/2π

                                    r = 16.3/6.28

                                    r = 2.5955 ft

2.- Calculate the volume

Volume = 1/3πr²h

-Substitution

Volume = 1/3(3.14)(2.5955)²(3.9)

-Simplification

Volume = 1/3(82.4966)

-Result

Volume = 27.5 ft³

My daughter is in 3rd grade. On a 3rd grade level how can she explain that 5/6 is greater than 5/8
blagie [28]
Well,5/6 is closer to one than 5/8 is,just add 1/6+5/6 and then you get 1,adding 1/8 to 5/8 is only 6/8,so that's how you can tell how it is greater! Hope this helps your daughter!

Which expression can be used to find measure angle R
Novay_Z [31]

Answer:

cos-1(-4/14)

Step-by-step explanation:

If

4.5=r

3.5=s

2=t

By law of cosines:

r^{2}=s^{2}+t^{2}  -2st cosR\\\\CosR= \frac{r^{2} -s^{2} -t^{2} }{-2st}  \\\\R=cos^{-1} (\frac{(4.5)^{2}-3.5^{2} -2^{2}  }{-2(3.5)(2)} )\\R= cos^{-1} (-\frac{4}{14}  )
