Answer:
153.94
Step-by-step explanation:
The formula for area is pi*radius^2
the radius is 7, so we do pi7^2 which is 49pi
49pi is 153.93804 which is 153.94 rounded to two decimal places
I'm guessing 15 mm is the side length.
V = a^3
Where 'a' is the side length.
V = 15^3
V = 3375
So the volume of the cube is 3375 mm^3.
The correct answer is 0.4
