A cylinder is inscribed inside of a square prism so that touches each face of the rectangle or prism. The empty space outside of

siniylev [52]

To solve take (Volume of Prism) - (Volume of Cylinder) = Epoxy

<span>V=(Area of base)(height)
</span>
Both they Cylinder and prism have a height of 40 inches
we can find the sides of the base of the prism by finding the diameter of the cylinder.

C=πd so 84.78 = πd.

Divide both sides by Pi (3.14)
$\frac{84.78}{3.14} = 27$

Half of the diameter is the radius to find the area of the cylinder base. 27/2=13.5

The volume of Prism is found by
$V=l*w*h$

27*27*40 = 29160 sq cm

The volume of cylinder is found by
$V= \pi r^{2}h$

using $3.14* 13.5^{2}*40$ = 22890.6

29160 - 22890.6 = 6269.4 cubic centimeters

Jen recently rode her bicycle to visit her friend who lives 6 miles away. On her way there, her average speed was & miles pe

Murrr4er [49]

Answer:

Let +s+ = her average speed going back home

+s+%2B+5+ = her average speed going to friend's house

Let +t+ = her time in hrs going back home

+2+-+t+ = her time in hrs going to friend's house

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

Equation for going to friend's house:

(1) +12+=+%28+s+%2B+5+%29%2A%28+2+-+t+%29+

Equation for going back home:

(2) +12+=+s%2At+

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

(2) +t+=+12%2Fs+

Plug this result back into (1)

(1) +12+=+%28+s+%2B+5+%29%2A%28+2+-+12%2Fs+%29+

(1) +12+=+2s+%2B+10+-+12+-+60%2Fs+

(1) +14+=+2s+-+60%2Fs+

(1) +14s+=+2s%5E2+-+60+

(1) +2s%5E2+-+14s+-+60+=+0+

(1) +s%5E2+-+7s+-+30+=+0+

(1) +%28+s+-+10+%29%2A%28+s+%2B+3+%29+=+0+ ( by looking at it )

(1) +s+=+10+ ( can't use the negative solution )

and

+s+%2B+5+=+15+

Going to friend's house: 15 mi/hr

Going back home: 10 mi/hr

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

check:

(2) +12+=+s%2At+

(2) +12+=+10t+

(2) +t+=+1.2+ hrs

and

(1) +12+=+%28+s+%2B+5+%29%2A%28+2+-+t+%29+

(1) +12+=+15%2A%28+2+-+t+%29+

(1) +12+=+30+-+15t+

(1) +15t+=+30+-+12+

(1) +15t+=+18+

(1) +t+=+1.2+ hrs
