[(1/3)^-2]/5*1=[(1/(1/3)^2)]/5=9/5

yeah there is u should be able to by clicking on the paper clip
Step-by-step explanation:
step 1. the area of a circle is A. A = (pi)r^2.
step 2. if the diameter is 8 cm then the radius is 4 cm.
step 3. A = (pi)4^2
step 4. A = 16(pi) = 50.24 cm.
Total distance = 20 km = 20 000 m
walk = 800 m
cycle = 20 000 - 800 = 19 200m
percentage of the journey =
x 100% = 96%
