Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft
Answer:
x=11
Step-by-step explanation:
Using the Exterior Angle Theorem. . .
(3x+8) + (2x+9) = (8x-16)
Solve to get x = 11
Obviously, 0.8, all you do is move over the decimal.
Answer:
8in³
Step-by-step explanation:
Volume is given as the product of surface area and height.
V=Ah
Where h is height and A is surface area. Here, the surface area is given 1 square inches and the height is 8 inches then the volume will be given as
V=1*8=8 cubic inches
Therefore, the volume of the bird feeder is equal to 8 cubic inches
