Answer:
Part 1) The surface area of the second solid is
Part 2) The volume of the second solid is
Step-by-step explanation:
In this problem we have
Part 1)
we know that
The ratio of the surface areas of two similar solids is equal to the scale factor squared
Let
x------> the surface area of the second solid (reduced solid)
y------> the surface area of the first solid (original solid)
z-----> the scale factor
we have
substitute and solve for x
Part 2)
we know that
The ratio of the volumes of two similar solids is equal to the scale factor elevated to the cube
Let
x------> the volume of the second solid (reduced solid)
y------> the volume of the first solid (original solid)
z-----> the scale factor
we have
substitute and solve for x

Answer:
Step-by-step explanation:
From the given information
Principal Initially Invested, P =$419
Annual Rate, r=9.2% =0,092
Time, t = 20 Years
Since it is compounded continuously, the value after t years is determined using the given model:
Substituting the given values
The value of the account after 20 years is (correct to the nearest cent)
