If (x,y) is reflected across the x axis, it becomes (x,-y)
so
(-4,2)
times -1 to y
(-4,-2)
A' is (-4,-2)
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

Scientific Notation is a way that scientists handle large numbers. Instead of writing something like 820932801, they'd write it as .
Here you go! I apologize if it makes no sense. I write my notes and practice problems super weirdly.
Haven't done one of these in forever. We avoid the quotient rule with an implicit logarithmic differentiation.
