need to find the radius first
area = pi*r^2
380 = PI *r^2
380/PI = r^2
r^2 = 121
r = sqrt(121) = 11 inches
radius is 11 inches
now calculate circumference:
c = 2*PI*r
C = 2 * 3.14 * 11
circumference = 69.08 = 69 inches
13u
Hope this helps!!!!!!!!!!!!
Random variable is used like this:
You close your eyes and point anywhere on the table to choose a number. Since the given random number table is made up of 3 digits, you only get the first two digits. We are also given a 70% of catching a fish, that means that the number you choose should not have a first two digit number greater than 70. If that happens, you go down to the next value. If you reach the bottom, you go up to the next column. This is done 3 times and multiplying the three numbers to get the chance for 1 trials. This is repeated 20 times and the average is obtained
Order of operations is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)
= (52 + 6) - (7 * 4) + 8
work inside parentheses first
= 58 - 28 + 8
work left to right now
= 30 + 8
= 38
SONYA'S MISTAKE
= (52 + 6) - (7 * 4) + 8
I think she added the 52, 6+4, multiplied 7*4 to equal 28, then added the 6+8 to equal 14
= 52 + 28 + 14 + 10
= 104
ANSWER: 38
Hope this helps! :)
