Answer:
Radius, r, is 3.75
Step-by-step explanation:
From the given diagram,
AB = 9
AC = 6 + r
BC = r
Thus applying the Pythagoras theorem, we have;
= 
+ 
= 
+ 
36 + 12r + = 81 +
collecting like terms,
12r = 81 - 36
12r = 45
r = 
= 3.75
r = 3.75
The radius is 3.75.
The volume is 134.4 and surface area is <span>276.8 hope this helps ! ^_^ dnt forget to mark me brainiest</span>
3,000 - 2,500 = 500
500/2,500 = 20%
The percent increase is 20%.
Hope this helps!
If it does it would be really helpful if you could make me brainliest.
Sin 30° equals 0.5 and as a fraction that would be 5/10 and 5/10 simplified is 1/2
