Answer:
the area is 254.47
Step-by-step explanation:
A=pi sign r²
d=2r
now we solve for the area
A=1/4 pi sign d²=1/4 times 3.14 times 18=254.47

Answer:
1. (x -3)(x -1)
2. (x -4)(x +1)
Step-by-step explanation:
1. The long division is shown in the first attachment. The quotient is (x -3), so the factorization is ...
x^2 -4x +3 = (x -1)(x -3)
__
2. The long division is shown in the second attachment. The quotient is (x -4), so the factorization is ...
x^2 -3x -4 = (x +1)(x -4)
Answer:
y < 1/21
Step-by-step explanation:
2/7, 4/14, 6/21
1/3, 2/6, 3/9, 4/12, 5/15, 6/18, 7/21
6/21 - 7/21 = 1/21
y < 1/21

Answer:
64.5 square inches
Step-by-step explanation:
The area of each of the two triangles can be found from the formula ...
A = (1/2)bh
<u>left triangle</u>
A = (1/2)(9.8 in)(8.6 in) = 42.14 in²
<u>right triangle</u>
A = (1/2)(5.2 in)(8.6 in) = 22.36 in²
Total shaded area is the sum of the areas of the two triangles:
(42.14 +22.36) in² = 64.5 in²
