Answer:
20,000m²
Step-by-step explanation:
If they jog 12 km/h for half an hour, they have covered.
12 X 0.5 = 6km in 10 circuits. Making 1 perimeter
6 / 10 =0.6 km (600 m).
To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.
So L = 2W
Perimeter = 2W + 2L
600 m = 2W + 2(2W)
600 m = 6W
W = 100 m
L = 200 m
Area = 100 X 200 = 20,000 m²
Answer:
First one: about $1.62 per pound
Second One: about $0.46 per pound
Step-by-step explanation:
9.70/6=1.62
5.50/12=0.46
Answer:
3. 2/3
Step-by-step explanation:
y=tan(2arctan(1/3))
= 2tan(arctan(1/3))
= 2*1/3
= 2/3
2πr= c
So π=3.14
56÷2= 28
2 x 3.14 x 28=c
87.12 x 2 = 174.24
The circumference is 174.24
