Answer:
3.14 ft² or 2,917 cm²
Step-by-step explanation:
To do this, we need to know the expression to calculate the area of a circle.
The area of any circle is:
A = πr²
Where:
π: value of pi, which is 3.14
r: radius of the circle, in this case 1 ft
Calculating the area in units of ft:
A = 3.14 * (1)²
A = 3.14 ft²
Now, if you convert the foot to cm we have:
1 * 30.48 = 30.48 cm
Solvinf for A:
A = 3.14 * (30.48)²
A = 2,917.15 cm²
Perpendicular means crossing so it would be a right angle. Therefore the 2 times will be
9:00 and 3:00
When the hour hand is at the 9 it will be perpendicular to the minute hand because they will be crossing paths if you extend the arms in both directions. The same with 3
Answer:
D. 0.65
Step-by-step explanation:
0.05 x 5=0.25
0.01 x 5=0.05
0.07 x 5=0.35
0.25+0.05+0.35=0.65
they all must pay 0.65 each
Answer:
1) Brazil - 190,000,000
2) Egypt - 77,000,000
3) Australia - 20,000,000
4) Singapore - 4,400,000
5) Luxembourg - 470,000
Dividing the number by 1,000 is the same as moving the decimal point left 3 points.
