Answer:
Exact: 9.42
Approx: 9
Step-by-step explanation:
The area of a circle is pi*radius^2 (pi=3.14 r=radius ^2= power of 2/squared)
The diameter is two times the radius. So, we need to divide the diameter by two for the first step of solving this.
6/2=3
Now, we know the radius is 3.
Let's square it:
3^2= 3*3
3*3=9
Now, the last step is to multiply it by pi (3.14)
3.14*3=9.42
There we go! The area is 9.42 feet!
Answer:
9 x 3 =27
Step-by-step explanation:
1. 8 = 8 => refrexive
2. If x = y, then y = x => symmetric
3. If x = y and y = 7, then x = 7 => transitive
4. 6 + 2 = 2 + 6 => commutative - addition
5. 5 ∙ 2 = 2 ∙ 5 => commutative - multiplication
6. 10 + (3 + 2) = (10 + 3) + 2 => associative - addition
7. 6(3 ∙ 5) = (6 ∙ 3)5 => associative - multiplication
8. 4(8 + 1) = 4 ∙ 8 + 4 ∙ 1 => distributive
9. 6 + 0 = 6 => identity - addition
10. 8 ∙ 1 = 8 => identity - multiplication
11. 1/2 ∙ 2 = 1 => multiplicative inverse
12. 5 ∙ 0 = 0 => property of zero
30x is the answer because
