Answer:
B) 75π cm³
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
Your cone has r = 5 cm and h = 9 cm. Putting these values into the formula gives ...
V = (1/3)π(5 cm)²(9 cm) = 75π cm³
Answer:
the Velocity of the plane is 100 mi/hr along the northeast direction
Step-by-step explanation:
According to the Question,
- Given That, the Initial velocity of the plane is 150 mi/hr along the east north direction and the wind is blowing at 50 mi/hr along the southwest direction
since the velocity of wind and plane is exactly opposite
- the relative velocity of the plane with respect to the wind is given by
, where
is the velocity of plane = 150mi/hr and
= velocity of wind = 50 mi/hr
- Therefore, Relative Velocity = 150-50 ⇒ 100mi/hr along northeast direction
Thus, the velocity of the plane is 100 mi/hr along the northeast direction
Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,

which is 40° and

which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,

:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Answer: 100°
