To calculate the number of shingles, we first calculate for the total area of the roof of Janice's house. From the figure, we can calculate the area of the two shapes: pyramid and a rectangular prism.
A(pyramid) = lw+l√[(w/2)²+h²]+w√[(l/2)²+h²]
A = 208 m²
A(prism) = 2(wl+hl+hw)
A = 293 m²
Total area = 501 m²
Number of shingles she needs = 501 m² / 2.25 m² =<span> 223</span><span>

Answer:
Step-by-step explanation:
16% is the answer.
440 is what percent of 2750?
440 = x/100 x 2750 (of means x or times in math)
440 = 2750x/100
440 = 275x/10
440x10 = 275x/10
4400 = 275x
4400/275= 275x/275
4400/275 = x
4400/275 = 16%
B = 3
3 to the second power is 9, and 4 • 9 = 36.

Answer:
39 pi cubic inches
Step-by-step explanation:
The volume of a cone is (1/3)(area of the base)(height).
Find the area of the circular base. The circumference of a circle is 
, so
Now that you know the radius of the circular base, you can find its area:
The height of the cone is 13. Time to use the volume formula.
