I think that it would be 3x + 1.
Answer:
exact: SA = 260π in.²
approximate: SA = 816.81 in.²
Step-by-step explanation:
SA = 2πr² + 2πrh
r = 10 in.
h = 3 in.
SA = 2πr(r + h)
SA = 2π(10 in.)(10 in. + 3 in.)
SA = 260π in.²
SA = 816.81 in.²
Answer:
Step-by-step explanation:
Use the distance formula:
For us that will look like this:
which simplifies to
and a bit more to
so
Answer:
9
Step-by-step explanation:
cos39= 7/x
x = 7/cos39
x= 9
The answer is 8,000 because 19 times 421 equals 7,888 and that estimated is 8,000
