Step-by-step explanation:
The formula for circumfrance is 2*(pi)*R and the formula for area is (pi)* R^2 or (pi) R-squared.
Circumfrance is 25.12 so....
25.12 = 2 * (pi) R........ you want to find R because you need it to find the area
R is about 4; it is 3.99797 .
You use the R that you goot from cirdumfrance to find area.
Area = (pi) (4)^2 = 50. 265
or is you prefer a more precise answer, Area = 50.2145

Two figures<span> that have the same shape are said to be </span>similar<span>. When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We calculate as follows:
3.9 / 1.3 = 9.6 / b
b = 9.6 x 1.3 / 3.9
b = 3.2</span>
