Answer:
t=1
Step-by-step explanation:
16-2t = t + 9 +4t
combine like terms
16-2t = 5t + 9
add 2t to both sides
16-2t+2t = 5t+9+2t
combine like terms
16=7t+9
subtract 9 from both sides
16-9=7t+9-9
combine like terms
7=7t
divide both sides by 7
t=1

A. 36 is the correct answer
Answer:
Area = πr²
Circumference = 2πr
Step-by-step explanation:
When given the radius r ,
Area of a circle A = πr²
Circumference of the circle C = 2πr
When given diameter d,
Area of a circle A = πd²/4
Circumference of a circle = πd
To find the radius r and d from area A,
r = sqrt(A/π)
d = sqrt(4A/π)
To find the radius r and diameter d from a given circumference C,
r = C/(2π)
d = C/π
Where d = 2r
