pi times radius equals the area of a circle
Percent means parts out of 100
x/100=x%
28/20=x/100
times both sides by 100
140=x
answer is 140%
Answer: "<span>
in²</span> " .
{that is: "
(2/15) in² . "}.
___________________________________________Explanation:___________________________________________The formula/equation for the Area of a rectangle: A = L * w ; in which: L = <span>
⅖ in ;
</span> w = ⅓ in;
___________________________Find the area; in a "fraction value" ;_______________________________ A = L * w ; → Substitute the given values for "L" (length) and "w" (width);
and solve for "A" (area) in the "form of a fraction:
__________________________________________________
A = (2/15) in * (1/3) in ;
→ A = [(2*1) / (5*3)] * in * in ;
______________________________________________________→ Answer: The area is: "
in² " .
{that is, "
(2/15) in² " .
}.

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.
19 x (12 + 2 + 3) = 323
323 - (2 x 2) - (3 x (14 + 2))
= 323 - 4 - 48
= 271
