as part of her shop class, Jules made the figure below out of pieces of wood. how much spave does the figure she made take up?

Answers

I suppose you want to find the Volume of this Figure.

you can separate it into two rectangular prisms
one that is 6 by 9 by 24
and the other that is 6 by 9 by 30

you multiply the three numbers to get the volume of each rectangular prism.
6 * 9 * 24 = 1296
6 * 9 * 30 = 1620

then we add the two numbers we got to get the overall volume of the figure
1296 + 1620 = 2916

Therefore the Figure takes up 2916 cm^3 of space.

Fine the area of a circle with a radius of 7 in. Write the formula, substitute, solve.

Answers

Formula: A=(pi)r^2

Substitution: A=3.14(7^2)

                     A=3.14(49)

Solve: A=153.86 in^2


*I personally like to use the pi sign on my calculator to multiply the radius squared by, but my keyboard did not have a pi sign.  Usually, the pi sign is more exact.  If you used the pi sign, your answer would be 153.94 inches^2.  Hope this helps!
