4(3/(8+1) = 4(3/9) = 12/9 = 4/3
4((3/8)+1) = 4(11/8) = 44/8 = 11/2
just depends on which way the equation is written
Answer:
≈ 62.8
Step-by-step explanation:
Using the equal ratios of
=
, that is
=
= 5, thus
5 × sector = 100π ( divide both sides by 5 )
sector = 20π = 20 × 3.14 = 62.8 units²
A
rational number is a number which can be expressed as a fraction whose
numerator and denominator are both integers and whose denominator is not equal
to zero. Rational numbers include all integers, fractions, mixed numbers, and
some decimal numbers.
Note : All terminating and repeating decimal
numbers are rational numbers because those numbers can be expressed as a
fraction. On the other hand, a non repeating number and non terminating
decimal, like square root of 2, is an irrational number.

Divide and then multiply by 100
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
