32\c b21is. correct answer
Answer:
300π in²
Step-by-step explanation:
The circle with diameter 20 inches has a radius of 10 inches, so an area of ...
A = πr² = π(10 in)² = 100π in²
The circle with a radius of 20 inches has an area of ...
A = πr² = π(20 in)² = 400π in²
The larger circle is larger by ...
(400π in²) -(100π in²) = 300π in²
Answer:
For the first one its: Volume = 402.12in³
For the second one its: Volume = 201.0619 in³
Step-by-step explanation:
For the first one work:
Volume = 3.1416 x 42 x 8
= 3.1416 x 16 x 8
For the second one work:
Volume = 3.1416 x 42 x 4
= 3.1416 x 16 x 4
Step-by-step explanation:
the question is asking for the volume of water in m^3 that will be in the pool when it is completely full.
we find this by multiplying the length times the width times the depth.
this gives us 50m×25m×2.5m= 3125m^3
