Since 18 is one twentieth of the angle of a full circle, 360, the circumference is 20 times the arc distance of 15, or 300
Answer:
B
Step-by-step explanation:
120 degrees is 1/3 of the circumference of a circle.
So the formula is 2 * pi * r * theta / 360
Arc length = 2* 12 * 3.14 * 120/360
Arc length =25.12 feet
Answer:
48 N
Step-by-step explanation:
The equation for force is
F = m * a
where F is force, m is mass, and a is acceleration
30N = m * 5m/s²
m = 6 kg
F = 6kg * 8m/s² = 48 N
Answer:
x = 11
Step-by-step explanation:
69° + (2x - 1)° = 90° (complementary angles)
69 + 2x + 1 = 90
Add like terms
69 - 1 + 2x = 90
68 + 2x = 90
Subtract 68 from each side
68 + 2x - 68 = 90 - 68
2x = 22
Divide both sides by 2
2x/2 = 22/2
x = 11
