Answer:

5.25 is the lenght of the arc AB.

Step-by-step explanation:

First, since we are told the answer should be expressed in radians, we need to convert the arc angle into radians, we do that by multiplying the angle by π and dividing by 180.

60° * π/180 = 1.05rad

Now, there is a simple formula to calculate the arc lenght, A = Ф*r, where:

A = arc lenght

Ф = arc angle (60°=1.05rad)

r = radius (5cm)

A = 1.05*5cm

A = 5.25cm

Answer:

400 square meters

Step-by-step explanation:

We can first solve this problem with each unit representing 1 centimeter, and then scale up at the very end. The shape that we have a parallelogram. The base is 8 cm, and the height is 2 cm. The formula for the area of a parallelogram is just bh, so the area of the parallelogram is 16 square centimeters. However, now we scale up. Since each centimeter correlates to 5 meters, each little box will correlate to 25 square meters. Therefore, 16 \cdot 25 = \boxed{400} square meters is our answer
