Answer:
The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
Substituting:
The volume of the frustum is given by the formula:
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
Answer:
18 degrees c
Step-by-step explanation:
subtract 17 from 35
Answer:
the two angles equal 180 degree
so 2x+2+5x+3=180
2x+5x+3+2=180
7x=180-5
7x/7=175/7
x=25

Acceleration = final speed - initial speed / time
Acceleration = 6 m/s - 0 / 3s
Acceleration = 6m/s / 3s
Acceleration = 2 m/s^2
