Answer:
d
Step-by-step explanation:
180-63 is 117
a line is 180 all together so therefore if we subtract the 63, we get the answer we want
1331= lwh or 1331= x^3
So take cube root of both sides and you will get 11.
Since the formula for area is length times width, the answer is 11x11 which equals 121.
So the square area of the base is 121mm^2
Answer:
area of shaded portion = 226.09 m²
Step-by-step explanation:
area of circle = πr² = (3.14)(18.6²) = 1086.314 m²
area of 123° segment = (123/360)(1086.314) = 371.157 m²
cos 61.5° = height/18.6 = 8.875
height of triangle = 8.875 m
sin 61.5° = 1/2base/18.6 = 16.346, base = 32.692 m
base of triangle = 32.692 m
area of triangle = 1/2bh = 1/2(8.875)(32.692) = 145.071 m²
area of shaded portion = 371.157 - 145.071 = 226.09 m²
