Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17
127.17 - (1/2 x 18 x 9) = 46.17cmsquared
X is equal to 8. The work for that is on the attached picture.
Answer:
48 in³
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = 
× area of base × height
here area of base = 24 and height = 6, so
V = × 24 × 6 = 8 × 6 = 48 in³
Answer:
2.5, 6 and 6.5 inches.
Step-by-step explanation:
5 + 12 + 13 = 30
So the shortest side = 5/30 * 15 = 1/6 * 15
= 2.5 inches.
The longest = 13 / 30 * 15 = 13/2
= 6.5 inches,
and the third = 12/30 * 15
= 6 inches.
5∛x + 4 = 44
5∛x = 40
∛x = 8
x = 8^3
x = 512
answer
C. 512
