Radius of circle = r = 5 cm
Angle made by the arc = Ф = π/4 radians
Area of sector = A = ?
The formula for the area of a sector is:
A = 0.5r²Ф
Using the values, we get:
A = 0.5 x (5)² x π/4
A = 3.125π cm²
Rounded of to nearest tenth, the area of the sector GHJ is 3.1π cm²
Answer:
y = 7
Step-by-step explanation:
-2y + 6 =-8 ( y - 6 )
-2y + 6 = -8y + 48
-2y + 8y = 48 -6
6y = 42
y = 42/6
y = 7
Answer:240 rotations
Step-by-step explanation: 1 rotation/45 seconds * 60 seconds / minute * 60 minutes / hour * 3 hours = 3600*3/45 = 240 rotations
(2x-2/2) = (15-6x)
2x-1 = 15 -6x
2x+6x = 15 +1
8x = 16
8x/8 = 16 /8
x = 2
