This is because 2÷3 = 0 . Six repeating but the Calculator rounds the last 6 to 7 because I can't fit all the repeating sixes in one calculator
Answer:
840 square feet
Step-by-step explanation:
13 x 20 = 260 x 2 = 520
10 x 12 / 2 = 60 x 2 = 120
10 x 20 = 200
520 + 120 + 200 = 840
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
It’s A
9.7 x 7 = 67.9
67.9 x 2 = 135.8
135.8 + 49 = 184.8
