Answer:
SA = 201 in^2
Step-by-step explanation:
The formula for surface area of a sphere is
SA = 4pi r^2
We know that the diameter is 8
To find the radius we cut the diameter in half.
r = d/2
r = 8/2 =4
Substitute in what we know.
SA = 4 *pi *4^2
= 4*pi*16
= 64*pi
Letting pi = 3.14
= 200.96 in^2
We want to round to the nearest whole number
SA = 201 in^2
Answer: 121/32in^3 or 3.78125in^3
Step-by-step explanation: Using the volume formula lwh, we get
11*11*(1/32)
or 121/32, which cannot be simplified further

Answer:
Step-by-step explanation:No
We know that ideally a Quaker oatmeal container should have 32 oz. oatmeal.
We also know that a difference of 0.5 oz. is acceptable, otherwise the container is rejected.
Let the amount of oatmeal actually present in the container be Q
32 - 0.5 < Q < 32 + 0.5
⇒ 31.5 < Q < 32.5
Hence, the equation that represents the highest and lightest acceptable weights is 31.5 < Q < 32.5.
