Answer:
1.2
Step-by-step explanation:
(I am not a good explainer)
Given:
The radius of inner circle = 13 yd.
The width of the shaded region = 8 yd
To find the area of the shaded region.
Now,
The radius of the outer circle = 13+8 yd = 21 yd
Formula
The area of a circle of radius r unit is
sq unit.

where,
= The area of the shaded region
= Area of the outer region
= Area of the inner region
Now,



sq yd
And,


sq yd
Therefore,
sq yd
sq yd
Hence,
The area of the shaded region 854.08 sq yd.
Answer:
12
Step-by-step explanation:
Fist convert the equation to vertex form
y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106
So the vertex is at (-7,-106)
