Answer:

91.7 inches to 1 decimal place

Step-by-step explanation:

We will use Pythagoras's theorem to find the height of the pyramid.

The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.

We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in

slant height = 92.3in

Therefore height = $\sqrt{92.3^{2} -10.2^2} =91.73in$

The height of the pyramid is 91.73inches to 1 decimal place

The height of the cylinder is 25 inches and the radius of its base is 5 inches. What is the surface area of this cylinder, in te

Vikentia [17]

ok you need formula for surface area.

SA = πrh+2πr^2

Plug in 25 and 5

SA = 2π(5)(25)+2π(5)^2

SA = 10pi*25 + 2pi(25)

SA = 250pi + 50pi

SA = 300pi

Hope this helps :)
