Hi!

---------------------------------------------------------------------------------------------

Area of a triangle = $(base * height)/2$

Area of a square = $(side)^2$

---------------------------------------------------------------------------------------------

QUESTION 1: Determine the area of the triangular face.

$\frac{bh}{2}$

$32(20)/2$

$640/2$

$320$

The triangular face is 320 square feet.

---------------------------------------------------------------------------------------------

QUESTION 2: Determine the surface area of the entire figure.

$a^2$

$32^2$

$1024$

Now, add the 4 triangular faces to the area of the square face.

$1024+320(4)$

$1024+1280$

$2304$

The total surface area is 1204 square feet.

Each sphere had a diameter of four feet. how much paint does it take to cover the sphere

Ostrovityanka [42]

It would take 64pi ft. sq. or approximately 201.06 ft. sq.

the formula for the surface area of a sphere is 4pi×r sq.

filling in for the radius (r) which is 4

4×pi×4 sq.
4×pi×16

then 16×4=64

therefore being 64 pi ft. sq.

but multiplying the pi would equal approx 201.06 ft. sq.

hope this helps
