What is the total area

333

Step-by-step explanation:

The area of the square is 81 bc 9x9 = 81,

the formula for a triangle is base x height divided by 1/2

the base 9 x height 14 = 126 then divide by 1/2(or 2) to get 63, because all 4 triangles are congruent do 63 x 4 to get the answer of all 4 triangles which is 252.

Then add the area of the square to the area of the 4 triangles, 81 + 252 = 333

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
