The radius is 10.4 cm. And the angle is 120 which is 1/3 of the circle.
Just use the area formula: 3.14 *r^2 to find the total area of 339.62 and then divide this by 3 to get 113.21. Then to subtract the triangle..find the area of the traingle which is 1/2 (10.4)^2 = 54.08. 113.21 - 54.08 = 59.13 which should be your answer

Answer:

10m/s,15m/s,20m/s,5m/s

Step-by-step explanation:

Speed = distance / time

a) distance = 100m , time = 10s

Speed = distance / time

Speed = 100m/10s

Speed = 10m/s

b) distance = 300m , time = 20s

Speed = distance / time

Speed = 300m/20s

Speed = 15m/s

c) distance = 700m , time = 35s

Speed = distance / time

Speed = 700m/35s

Speed = 20m/s

d) distance = 1000m , time = 200s

Speed = distance / time

Speed = 1000m/200s

Speed = 5m/s

A container holds 10 gallons of water. If 5/8 of a gallon is added to the container each hour, how many hours would it take to f

Morgarella [4.7K]

The answer is 16 hours. This is because 5/8 is equivalent to .625 so we divide the total capacity by that increment and we get 16.
