If the area of a circle is 20.4 units squared, what is the radius?
dmitriy555 [2]

Answer:

r = 2.55

Step-by-step explanation:

The formula for finding the radius of a circle using the area is r = √A/π

with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).

So the equation should look like this:

r = √(20.4/3.14)

Find the quotient of 20.4/3.14 and round to the nearest tenth

r = √6.5

Find the square root and round to the nearest hundredth

r = 2.55

Butoxors [25]

Answer:

Adults = x

Students = y = x + 40. 40 more student than adult

Adult = $8, Student = $6

Total for Adults = 8*x = 8x

Total for students = 6*y = 6y

Total = $1920

8x + 6y = 1920

Hence system of equations are:

y = x + 40

8x + 6y = 1920

b)   1106

Explanation:

Hex addition can be achieved through repeated subtraction of 16 from the decimal sum of same place values of hex numbers until the result is reached to one of the hex digits from 0 to F. The carry increases by 1 where each time the number 16 is subtracted from the hex numbers decimal sum. The below example lets you understand how to perform hex numbers addition

(a)   6B4 + 3FE

                   6 B 4

               +  3 F E
