The surface area of the large sphere is 128π cm²
<h3>Complete question</h3>
Two spheres have volumes of 8π cm3 and 64π cm3. If the surface area of the smaller sphere is 16π cm2, what is the surface area of the larger sphere?
<h3>How to determine the larger area?</h3>
The given parameters can be represented using the following ratio:
Small Area : Large Area = Small Volume : Large Volume
Substitute the given parameters
16π : Large Area = 8π : 64π
Express as fraction
Large/16π = 64π/8π
Multiply both sides by 16π
Large = 128π
Hence, the surface area of the large sphere is 128π cm²

Answer:
The last one I believe
Step-by-step explanation:
If the shirt is $8.95 and the sandwich is $7.25 then the books are $6.09 each which means they are $13.08 together.
Solving the inequality 
we get value of x: 
Step-by-step explanation:
We need to solve the inequality 
and find value of x.
Solving:
Multiplying -3 with the terms inside the bracket
Converting mixed fraction into improper fraction:
Adding 11.98x on both sides
Subtracting 24.6 on both sides:
Divide both sides by -0.02 and reverse the inequality i.e < sign is changed to > due to division of (-) sign.
So, solving the inequality we get value of x:

Answer:
72 m²
Step-by-step explanation:
A = 4x(5+4+5) + (4x4)
= 4x14 + 16
= 56 + 16
= 72 m²
