1 pound = 16 ounces
16+9 = 25 ounces
2 /25 = 0.08 per ounce
it costs 8 cents per ounce
Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw
so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2
split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so
bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3

Circumference is 2 x Pi x r.
12 x 3.14 is 12 x Pi
12 / 2 is r
Find a circle with radius of 6 inches. Radius is distance from the Center S to any outside part of the circle
Answer: k=225/2
Decimal form: k= 112.5
Mixed number form: k=112 1/2
Exactly the same way you would do it if it were a proper fraction . . .
multiply the numerator by the whole number, and then clean up
the fraction.
