Ierofanga [76]

Answer:

64 books

Step-by-step explanation:

The first step is to find the number of books that will fit in the shelve per foot

= 40/5

= 8

Therefore the number of books that will fit perfectly in 8-foot shelf can be calculated as follows

= 8×8

= 64

Hence 64 books would fit in 8-foot shelf

9 : 2 = 18 : 4

As: 9 x 2 : 2 x 2 = 18 : 4

--------------------

36 : 8 = 18 : 4

As: 18 x 2 : 4 x 2 = 36 : 8

--------------------

72 : 16 = 18 : 4

As: 18 x 4 : 4 x 4 = 72 : 16

a silo is shaped like a cylinderwith a cone on top. the radii of the bases of the cylinder and cone are both equal to 8 feet. th

Ymorist [56]

Answer:

5430.85 square feet

Step-by-step explanation:

Height of the cylindrical part of the cilo = 25 feet

radius of the base cylindrical part of cilo = 8 feet

Now volume of cylindrical part of cilo = $\pi r^{2} h$

Volume of cylindrical part of cilo = $\pi(8^{2})25$ = $1600\pi square feet$

Now,

Height of the conical part of cilo = 6 feet

Radius of the conical part of cilo = 8 feet

Volume of the conical part of cilo = $\frac{1}{3}\pi (8^{2})6$ = $128\pi square feet$

Volume of the entire cilo = $1600\pi + 128\pi = 1728\pi$

since $\pi =\frac{22}{7} therefore,$

volume of entire cilo = $\frac{22}{7} (1728)$ = 5430.85
