Answer:
Step-by-step explanation:
The formula of a lateral area of a cone:
r - radius
l - slant height
The formula of a surface area of a cone:
We have r= 8in and l = 21in. Substitute:
Answer:
y = -2x - 8
Step-by-step explanation:
<u>Use the point slope form: (y - y1) = m(x - x1)</u>
(y - (-4)) = -2(x - (-2))
y + 4 = -2(x + 2)
y + 4 - 4 = -2x - 4 - 4
y = -2x - 8
Answer: y = -2x - 8
Answer:
As shown in picture, the area is divided into 4 parts: 3 triangles and 1 rectangles.
Total area:
A = smallest triangle + medium triangle + largest triangle + rectangle
= 2 x 2 x 1/2 + 2 x 6 x 1/2 + 4 x (2 + 2 + 6) x 1/2 + 2 x 2
= 2 + 6 + 20 + 4
= 32
Hope this helps!
