The angles converted to radian are as follows:
30° = 0.523599 rad
45° = 0.785398 rad
90° = 1.5708 rad
180° = 3.14159 rad
<h3 /><h3 /><h3>Degree to radian conversion:</h3>
Therefore,
a.
1° = 0.0174533 rad
30° = ?
cross multiply
angles in radian = 30 × 0.0174533 = 0.523599 rad
b.
1° = 0.0174533 rad
45° = ?
angles in radian = 45 × 0.0174533 = 0.785398 rad
c.
1° = 0.0174533 rad
90° = ?
angles in radian = 90 × 0.0174533 = 1.5708 rad
d.
1° = 0.0174533 rad
180° = ?
angles in radian = 180 × 0.0174533 = 3.14159 rad

5 times 7 =45
42 + 45 = 87
Answer:
<em>The x-coordinate is changing at 10 cm/s</em>
Step-by-step explanation:
<u>Rate of Change</u>
Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:
We have
Or, equivalently
We need to know the rate of change of x respect to t. We'll use implicit differentiation:
Solving for dx/dt
Plugging in the values x=1, y=3, dy/dt=5
The x-coordinate is changing at 10 cm/s
The surface area of the sphere is given by the equation
,
where A is the surface area and r is the radius.
We want to find the volume of the sphere, which is given by the equation
,
where V is the volume and r is the radius.
Looking at these equations, we see that they both involve the sphere's radius. If we know what r is, we can calculate the volume.
We know that the sphere's surface area is . Plugging that in for A in the surface area equation, we get
, then divide by
, then divide by 4
, then take the square root of both sides
So the radius of the sphere is 3. Plugging this into the volume equation,
, simplify terms
, multiply by 27
So the volume of the sphere is .
