Answer:
A=777.54
Step-by-step explanation:
What you do is use the formula which is
a=2pirh+2pir^2.
The radius is half the diameter and the diameter is 15 so you take 15 and divide it by 2 to get 7.5.
The height is 9 m.
A=2(3.14)(7.5)(9)+2(3.14)(7.5)^2=777.54 m.

Answer:
Tara is 27 and Adam is 31.
Step-by-step explanation:
Tara: x years old
Adam: x+4
Subtract the five years to get their current age
x-5 and x+4-5
x-5 and x-1
(x-5) + (x-1) = 48
x-5 + x-1 = 48
2x - 6 = 48
2x= 48+6
2x= 54
x= 27
Tara is 27 and Adam is 31
