Answer:
12.57 in^3
Step-by-step explanation:
The easiest way to do this is to find the area of the circle surface and multiply it by the height
to find area the formula is pi r^2 and we are given the radius
so we plug in pi(2^2)=pi(4)= roughly 12.57
then we multiply the area by the height which is 1 so it would be the same
12.57(1)=12.57
You need to put a picture but than I would love to answer it
Answer:
<u>67 m/s</u>
Step-by-step explanation:
Formula for range :
- u = initial velocity
- θ = angle of launch
- g = gravitational acceleration
Solving with the given values :
- 400 = u² x sin60° / 9.8
- u² x √3/2 = 3920
- u² = 7840/√3
- u² = 4526.4
- u = <u>67 m/s</u> (approximately)
1) domain of the first is ( R ) because of its root(3) and its range is (R) because of its root again
2)and domain of the last , is [0,+infinity)
and for its range , you can draw it such as picture and will be [0,- infinity)
