Answer:
1) x+6 2)y-4 3)36
Step-by-step explanation:
(x+6)² + (y-4)² = 36
By definition, the area is given by:

Where,
w: width
l: length
We have two expressions for the length:
Since the length is the same, we equate both expressions:

From here, we clear the value of c:


Then, we have that the width is given by:

Substituting the value of c we have:

Finally, the area is given by:

Answer:
he should order 140 square feet
Answer:
V = 1206.3 
Step-by-step explanation:
This shape is made up of a cylinder on the bottom and a cone on the top. We'll find the volumes of these shapes separately and then add them together.
Volume of a cylinder = area (of the base) x height
Substitute in the formula for the area of a circle.
V(cylinder) = 
x h
Substitute in the values for the radius (8) and height (4)
V(cylinder) =
x
x 4
Evaluate using a calculator
V(cylinder) = 804.2477
To the nearest tenth, V(cylinder) = 804.2
Volume of a cone =
. This is the area of the circular part of the cone (
), multiplied by the height from the point to the base, all divided by 3.
Substitute in the values for the radius of the circle (8) and the height (6)
V(cone) =
(On the top it's
x
x 6)
Evaluate using a calculator
V(cone) = 402.1239
To the nearest tenth, V(cone) = 402.1
Total volume = V(cylinder) + V(cone)
= 804.2 + 402.1
= 1206.3
