Answer:
Step-by-step explanation:
Radius =6 ft
Area of circle = πr²
= 3.14 * 6 * 6
= 113.04 ft²
base = 10.39 ft
height = 6+3 = 9 ft

= 46.76 ft²
Area of the shaded region = area of circle - area of triangle
= 113.04 - 46.76
= 66.28
= 66.3 ft²
Answer:
(5 x 10^7)(6 x 10^4)= 3 x 10^12 is the answer in scientific notation
Step-by-step explanation:
6 for the two bases = 12
6 x 2 = 12 for the 4 faces = 48
48+12 = 60 cm^2
You would say that the side ADAC is congruent to ABCA because the two triangles where it is split in half are congruent as well.
