Answer:
4.5X10^-3
Step-by-step explanation:
Scientific notation formula= x.x times 10^x
Answer:
1 out of ten
Step-by-step explanation:
so if there are ten sides and all are numbered 1-10 then 5 is only one tenth.
The pool has a diameter 20 ft so: r = 10 ft.
The pool cover extents 12 inches beyond the edge of the pool.
12 inches = 1 foot
Therefore, the radius of the pool cover is : r = 10 + 1 = 11 ft.
a. The area of the pool cover:
A = r² π = 11² π = 121 π ft²
b. The length of the rope:
l = 2 r π = 2 · 11 π = 22 π ft.
