A,C,and D are all correct
Answer:
21.07 yd^2
Step-by-step explanation:
The width of the rectangle is also the radius of the semicircle. The length of the rectangle is 2 radii, or 14 yd.
The area of the shaded region is the same as the area of the semicircle subtracted from the area of the rectangle.
area of shaded region = area of rectangle - area of semicircle
A = LW - (1/2)(pi)r^2
A = 14 yd * 7 yd - (1/2)(3.14)(7 yd)^2
A = 98 yd^2 - (1.57)(49 yd^2)
A = 98 yd^2 - 76.93 yd^2
A = 21.07 yd^2

Answer:
= -42a⁶
Step-by-step explanation:
-7a⁵. 6a = -7a⁵ × 6a
Therefore;
We multiply; -7 × 6 = -42
then; a⁵ × a = a⁶
Thus; we have -42 a⁶
Hence; <u>-7a⁵ × 6a = -42 a⁶</u>
