Answer:
Step-by-step explanation:
surface area of sphere=a
4pir^2=a
r^2=a/4p
r=root(a/4pi)
if radius is doubled
r1=2root(a/4pi)
r1^2=4(a/4pi)
a/a1=(4pia/4pi)/(4pi 4a/4pi)=1/4
so a is increased by 4 times
It is 18 because the radius is half the diameter and 9 x 2 = 18.
1/25
think of it as 4/100
4 goes into 100 4 times
1/25+1/25+1/25+1/25=4/100
