i cant figure this one out because instead of using the pi button you have to use 3.14 could someone please help me solve this?

total surface area = 848.2293m^2

volume=550π  or 1727.88

Step-by-step explanation:

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for

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
