Answer:  30^{\circ}

Step-by-step explanation:

According to the given information:

Minor arc = 150°

Major arc = 360°-150°=210°

Since angle made by tangents is equal to the half of the difference between the major and the minor arcs made by them.

Let x be the viewing angle (angle made by tangents):

Then,

x=\dfrac{1}{2}(\text{Major arc -Minor arc})\\\\\Rightarrow\ x=\dfrac{210^{\circ}-150^{\circ}}{2}\\\\\Rightarrow\ x=\dfrac{60^{\circ}}{2}\\\\\Rightarrow\ x=30^{\circ}

Hence, the viewing angle should be used=30^{\circ}

How do I find the volume of a triangular prism?
soldier1979 [14.2K]

Answer:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Assume that the radius r of a sphere is expanding at a rate of 40 cm/min. The volume of a sphere is V = 4 3 πr3 and its surface
Scrat [10]

Answer:

The rate of change in surface area when r = 20 cm is 20,106.19 cm²/min.

Step-by-step explanation:

The area of a sphere is given by the following formula:

A = 4\pi r^{2}

In which A is the area, measured in cm², and r is the radius, measured in cm.

Assume that the radius r of a sphere is expanding at a rate of 40 cm/min.

This means that \frac{dr}{dt} = 40

Determine the rate of change in surface area when r = 20 cm.

This is \frac{dA}{dt} when r = 20. So

A = 4\pi r^{2}

Applying implicit differentiation.

We have two variables, A and r, so:

\frac{dA}{dt} = 8r\pi \frac{dr}{dt}

\frac{dA}{dt} = 8*20\pi*40

\frac{dA}{dt} = 20106.19

The rate of change in surface area when r = 20 cm is 20,106.19 cm²/min.
