Answer:
The approximate value of the area is
Step-by-step explanation:
we know that
The area of the circle (landing pad) is equal to
we have
substitute
----> exact value of the area
Find the approximate value
assume
------> approximate value of the area
The ratio of surface area is equal to the ratio of the square of the corresponding dimensions. And ratio of volumes of two solids is equal to the cube of the ratio of the corresponding dimensions .
We start with the relation between ratio of surface area and ratio of corresponding sides. That is
Here x and y are the corresponding sides .
Let the volume of the smaller one be v
So for the smaller solid, volume is 272 . And the correct option is the first option .
