B I think that is the answer. If its not please let me know.
Answer:
1544.1 ft to the nearest tenth.
Step-by-step explanation:
We have a triangle where we have to find the hypotenuse and the opposite side to the given angle = 1200 feet.
So we use the sine function ( sin = opp / hyp).
sin 51 = 1200 / h
h = 1200 / sin 51
h = 1544.111 ft.
Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
