Answer:1.1 ft^2
Step-by-step explanation:
Φ=55°
Radius=r=4
π=3.14
Area of segment=area of sector - area of triangle
Area of sector=Φ/360 x π x r x r
area of sector=55/360 x 3.14 x 4 x 4
Area of sector=(55x3.14x4x4) ➗ 360
Area of sector=2763.2 ➗ 360
Area of sector=7.7 ft^2
Area of triangle=0.5 x r x r x sinΦ
Area of triangle=0.5 x 4 x 4 x sin55
Area of triangle=0.5 x 4 x 4 x 0.8192
Area of triangle=6.6 ft^2
Area of segment=area of sector - area of triangle
Area of segment=7.7-6.6
Area of segment=1.1 ft^2
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the ordered pair for the center.
(x - (- 3))² + (y - 6)² = 10²
(x + 3)² + (y - 6) = 100
A. & D. are the correct answers
To answer this, you square the first 2 numbers in the sequence, and then add them together. You then square the 3rd number and put it equal to the first numbers that you added together. If the two sides equal each other, it is correct!
Ex.:
10, 24, 26
10^2 + 24^2 = 26^2
100 + 576 = 676
676 = 676
18, 24, 30
18^2 + 24^2 = 30^2
324 + 576 = 900
900 = 900
Volume of a cylinder is V=pi r^2h =42.41
3/4 *42.41=31.81ft
