1. A farmer wants to make a pool for his ducks with circumference of 45 m.What is the area of the pool?
2. The radius of the Earth is 6,371 km. What is its circumference?
1.
circumference = diameter . 3,14
45 m = diameter . 3,14
diameter = 45m : 3,14
diameter = 14,33 m
area = (radius)2 . 3,14
radius = diameter : 2
radius = 14,33 : 2
radius = 7,16 m
area = (7,16m)2 . 3,14
area = 161,22 m2
circumference = radius . 2 . 3,14
circumference = 6,371 . 2 . 3,14
circumference = 12,724 . 3,14
circumference = 40,00988 km

Trả lời :
Bài 1 :>>>
circumference = diameter . 3,14
45 m = diameter . 3,14
diameter = 45m : 3,14
diameter = 14,33 m
area = (radius)2 . 3,14
radius = diameter : 2
radius = 14,33 : 2
radius = 7,16 m
area = (7,16m)2 . 3,14
area = 161,22 m2
Bài 2 :
circumference = radius . 2 . 3,14
circumference = 6,371 . 2 . 3,14
circumference = 12,724 . 3,14
