Answer:

Step-by-step explanation:
Given
Shapes: Cube and Cone
Required
Determine the volume
First we calculate the volume of the cube

Where
l = side length = 5.1


Next, calculate the volume of the cone using:

Where
h = 5.1



So, we have:





The volume of the figure is:




Answer:
Cos b
Step-by-step explanation:
1/2[sin(a+b)+sin(a-b)]
1/2[sin a cos b +cos a sin b + sin A cos B - cos A sin B]
1/2[2sin a cos b]
sin a cos b
1:1, because there’s a same number of both !
The answer is 6⁴.
Exponent is the number of times the factor is being multiplied. For example:
x * x = x²
x * x * x = x³
x * x * x * x = x⁴
....
So:
6 * 6 * 6 *6 = 6⁴
It should be for seconds...
30min(60sec/min)=1800s
