The area of a pentagonal base is 125/tan 60°m^2. its height is 15 m. find the volume
the area of a hexagonal base is 54/tan 30° m^2. its height is 8 m. find the volume
please help :) I just moved schools and I'm a month behind them. no idea what I'm doing.

a = 4, h = 3

Output : Surface Area: 155.138443

        Volume: 124.707657

Input : a = 5, h = 10

Output : Surface Area: 429.904

        Volume: 649.519

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
