You forgot to put the decimal in there so i could round it
3^(-2) = 1/(3^2) = 1/(3*3) = 1/9
The rule used here is x^(-y) = 1/(x^y) to make the exponent positive.
3^2 turns into 3*3 because the exponent 2 tells us how many copies of the base '3' to multiply out.
Answer:
The answer to the question is 50.28 feet²
Step-by-step explanation:
Here, is why the answer to the problem is 13.72!
The area of the shaded region is:-
Area of total region - Area of the circular region
Area of total region is 8² so it is 64 feet²
Area of Circular region formula is πr²
Substitute the values, for the formula and it is π4² = 22/7 × 16
→ 352/7
⇒ 13.72 Feet²
Therefore, the area of the shaded region is 13.72 Feet²
(Now, we subtract the two values)
64 - 13.72
⇒ 50.28 Feet²
I hope this answer helps!
Answer:
the area is 10 feet by 10 feet, 100 feet²
subtract the area of the circle from this.
you get it by A = r² * pi
so 5² * 3.14159...
=78.5398163397
100-78.5398163397
is roughly 21.46 square feet
