A pyramid has square base with side s. The height of the pyramid is 2/3 that of lts side. What Is the expression for the volume of the pyramid?
A. V=2s^2
B. V=2s^3
C. V=2/3s^2
D. V=2/9s^3
E. V=1/3s^3

D. V=2/9s^3

Step-by-step explanation:

D.

x=0

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
