Sphere
c=2pir
v=(4/3)pir^3
SA=4pir^2
so
first one
c=50
50=2pir
25=pir
25/pi=r
SA=4pir^2
SA=4pi(25/pi)^2
SA=4pi625/(pi^2)
SA=2500/pi
SA=795.8
D
2nd euqtion
V=2254pi
(4/3)pir^3=2254pi
divide both sides by pi
(4/3)r^3=2254
ties both sides by 3/4
r^3=1690.5
cube root both sides
r=11.9126
SA=4pir^2
SA=4pi11.9126^2
SA=4pi141.909
SA=567.636pi
SA=1783.3
D is answer
3rd
find side legnth
cube root each since V=side^3
volume 729 to 6859 is side legnths
9 to 19
every 9 units turns to 19
answer is A
