A wedge is two inclined planes placed back to back
Answer:
24432.193
Step-by-step explanation:
Volume of sphere = 4/3 pi x cube of radius
Radius =18ft , pi = 3.142
Volume = 4/3 x 3.142 x 18 x 18 x 18
Volume = 1.3333 x 3.142 x 5832
Volume = 24432.19ft3
Volume =24432ft3 to the nearest whole number

Answer:
11 units
Step-by-step explanation:
The height of a trapezoid is the distance between the parallel bases.
__
Here, one base lies on the horizontal line y=5, and the other lies on the horizontal line y = -6. The distance between them is ...
5 -(-6) = 5 +6 = 11
You can also find this distance by counting the grid squares between the two parallel lines.
The height of the trapezoid is 11 units.
_____
<em>Additional comment</em>
The base lengths are ...
AB = 2 -(-5) = 7
CD = 8 -(-7) = 15
The area is 1/2(b1 +b2)h = (1/2)(7 +15)(11) = 121 square units.
Answer:
her equation should be a² + 3² = 4²
Step-by-step explanation:
a² + 3² = 4²
a² + 9 = 16
a² = 7
a = 
a ≈ 2.6 inches
(10^2 +10^2)^.5 = 10*(sqrt2)
