Answer:
2122.64 in^2
Step-by-step explanation:
Use the formula for the area of a circle: A=πr^2
The radius will be half the width of the cloth so 52÷2=26
26^2=676
Multiply by π given as 3.14
676×3.14=2122.64 square inches.
The symbol (carat) ^ is used to indicate an exponent when the keyboard doesn't have superscript.
To find a fraction's lowest term, just simplify them and divide to find the decimal form.
12/24 = 1/2, 0.5
3/30 = 1/10, 0.1
10/8 = 5/4, 1.25
34/20 = 17/10, 1.7
14/8 = 7/4, 1.75

Answer:
r = -1 or r = 13/3
Step-by-step explanation:
Solve for r over the real numbers:
abs(10 - 6 r) = 16
Split the equation into two possible cases:
10 - 6 r = 16 or 10 - 6 r = -16
Subtract 10 from both sides:
-6 r = 6 or 10 - 6 r = -16
Divide both sides by -6:
r = -1 or 10 - 6 r = -16
Subtract 10 from both sides:
r = -1 or -6 r = -26
Divide both sides by -6:
Answer: r = -1 or r = 13/3
