Answer:
40/3 pi
Step-by-step explanation:
Volume of a cone = 1/3 *pi*h*r^2 , where h = height, and r = radius.
diameter = 2 radius, so radius = 8/2 = 4
The height = 10, so plug these values into the equation:
1/3 * pi * 10 * 4 =
40/3 pi
Answer:
there are 14 books in the box now
Step-by-step explanation:
12-4=8
8+6=14
14 books
2^3 = 8
3^2 = 9
8 * 9 * 5 = 360
15 is a factor of 360, so the answer would be <span>1. Fifteen is a factor of the number because both 3 and 5 are prime factors</span>
Answer:
x=5
Step-by-step explanation:
2 2/7 : (0.6x) :: 4/21 : 0.25
Hence, as it is in a perfect proportion, we may use the proportion method..
We multiply the extreme terms and the moderate(near) ones and equalise them.
Hence,
(2 2/7)×(0.25) = (0.6x × 4/21)
16/7 × 25/100 = 6x/10 × 4/21
16/7× 1/4= 3x/5 × 4/21
(16/7 × 1/4)/(4/21) =3x/5
16/7×1/4×21/4×5/3=x
1/7×21×5/3=x
x=5
