Answer:
9
Step-by-step explanation:
|9| = 9
Absolute value is distance from zero. 9 is 9 away from 0. BRAINLIEST? :')
Answer:
2713
Step-by-step explanation:
The volume of a cylinder is base * height. That means the whole cylinder's volume is 8^2 * 18 * pi = 1152 pi
The volume of a sphere is (4/3)(pi)(r^3) = (4/3)(pi)(6^3) = 288 pi
Cylinder - Sphere = Shaded Volume
1152pi - 288pi = 864pi
Substitute 3.14 for pi, and you get
864(3.14) = 2712.96, which rounds to 2713

Answer:
d. 175 square inches
Step-by-step explanation:
If we assume the base is square and all triangular faces are congruent, then the lateral area of the figure is that of four triangles. Each triangle has an area that is half the product of its base and height:
A = (1/2)bh = (1/2)(7 in)(9 in) = 31.5 in^2
The area of the square base is the product of its length and width, both of which are 7 in.
A = lw = (7 in)(7 in) = 49 in^2
So, the total surface area is that of the base plus the four sides:
surface area = (49 in^2) + 4(31.5 in^2) = 175 in^2 . . . . . matches choice D
