Which formula will you used to solve for the surface area of this figure S A = 1/2 P h+2B
S A = P h +2B
A= L x W
A = bh/2

Step-by-step explanation:

Surface area = area of triangles x 4  + 2(side base)

                     = 1/2 b h (4) + b*b

                     = 2 b h + b²

where:

base (b) = 4 cm

side length height (h) = 6 cm

plugin values into the formula:

therefore, the formula to calculate surface area

of a square base pyramid = 2(b)h + b²

3, nah jk it's 2

step-by-step explanation:

it is 3 cause i'm sanic

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
