Answer:
s=14(116)
s = 1624
(This is the arc length for <u>RS</u>)
The line T to R cuts the circle in half. Half of a circle in degrees is 360/2. Which is 180.
Now we take the known angle and subtract it from 180 to get the unknown angle which is the angle of RS.
[180-64 = 116]
Arc length = radius * theta
Arc length = 14 * 116 = 1624
[FOR TS BELOW]
s=r(theta)
s= 14(64)
s = 896 (arc length for <u>TS</u>)
Answer:
Step-by-step explanation:
substitute and solve:
100 = bh
100 = b(2b)
100 = 2b²
50 = b²
b = √50
b = √(25 * 2)
b = 5√2
solve for h:
h = 2b
h = 2(5√2)
h = 10√2
if you are told to round to 1 DP :
b ≈ 7.1 m
h ≈ 14.1 m
This balloon can travel 450 km every hour. You travel for 2.5 hours, so multiply:
450km/h * 2.5h = 1125km
