The diameter of the the EPCOT Ball at Disney is 165 feet. Approximate the volume of the EPCOT Ball. Round to the nearest foot.

2352071 ft ^3

Step-by-step explanation:

formula for volume of a sphere is

V= 4/3 * * r ^3

V = 4/3 * * 82.5 ^3 = 2352071 ft ^3

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
