Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
Answer:
x= -8 and so y=35.....solving equation
Answer:
x = 4
Step-by-step explanation:
we know that 72 and (2x + 10) add up to 90
90-72 = 18
(2x + 10) = 18
2x = 8
x = 4
The geometry sequence has the equation 
.
The 5 represents the first number of the sequence and the 3 represents the common ratio.
a(5) = 
answer: 405
3/4=0.75
0.75 would be equal to 3/4
