if the question is what is the are of the circle without the rectangle inside it, then we could solve it easily using the Mathematical formula for A Circle's area which is

$\pi {r}^{2}$

since a radius is half a diameter, and the diameter is 8cm, the radius becomes 4 cm

Step-by-step explanation:

π×4^2

3.14×16

An astronaut standing on a platform on the moon drops a hammer. The hammer falls 6m vertically in 2.7seconds. What is accelerati

Fantom [35]

6m Divided by 2.7 Seconds
6/2.7=2.22222222222
2.22222222 Meters per second is end velocity
the change in velocity is Start velocity (0m/s) - end velocity (2.222222222m/s)
So the Change in velocity is 2.222222222m/s
To find acceleration it is Change in velocity (2.2222222m/s)/Time (2.7m/s)
2.222222222222/2.7=0.82304526749
acceleration=0.82304526749 Meters per second Squared
This also would make sense as we already know acceleration is less on the moon.
Answer=0.82304526749m/s ²
