So remember that the area of a circle is A = π * r^2, with r = radius. In this case, the radius is 1.5, and with that info our equation is A = π * 1.5^2 .
For this, all you need to do is solve the exponents, and your answer is A = 2.25π yds^2
True!
90 hundreds is equal to 900 tens
90 times 100= 9000
900 times 10= 9000
9-6 is 3 and the m moves to the new number so it would be 3m then you multiply 3 and 7 and you would get 21m. So therefore you answer is 21m
3x - 11 = -1x -75
3x = -1x -75 +11
3x + 1x = -75 + 11
4x = -64
x = -64/4
x = -16
Answer:
- a = 1.11
- B = 105.4°
- c = 2.95
Step-by-step explanation:
B = 180 -A -C = 105.4 . . . . sum of angles in a triangle is 180°

The missing side lengths can be found from the Law of Sines:
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) = 2.46·sin(21.2°)/sin(53.4°) ≈ 1.11
Likewise, ...
b = c·sin(B)/sin(C) = 2.46·sin(105.4°)/sin(53.4°) ≈ 2.95
