Answer:
r = 
r = 17.2 cm
Step-by-step explanation:
∵ The area of the circle A = πr²
∴ r² = A/π
∴ r = √(A/π)
∵ A = 54 cm²
∵ π = 22/7
∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm
3/8 times 3/1 is 9/8 or 1 1/8 inches.
Answer: X= 30
Step-by-step explanation: So I must admit that is a really weird place to put that line, but if this is a complementary angle and the first angle is 30 degrees, then the other angle should be 60 degrees. 60/2 is 30, so therefore x=30
