Answer:
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
<span>(1.3t3 + 0.4t2 – 24t) + (8 – 18t + 0.6t2)
In adding polynomials, make sure that each term is grouped together.
1.3t</span>³ + 0.4t² - 24t
<u> + 0.6t² - 18t + 8</u>
1.3t³ + 1.0t² - 42t + 8
In a polynomial equation, arrangement of each term is dependent on the exponential number. It should be from the highest exponent to the lowest.
$10740
This is because that amount multiplied times .06 is equal to the answer. <span />
The problem rewritten is 77a-42c
Multiply each term in the parentheses by 2x:-
= 12x^3 + 8x^2 - 6x Answer
