4/3 as a fraction is 1 1/3. The volume of a circle is not a thing, so I am going to assume your asking volume of the balloon.
9 = radius
The volume is of the balloon is 4/3 x 9 x 9 x 9 x 3.14 (pi)
Volume = 3052.08 cubic inches
If you are asking for area of circle
Area of Circle = 9 x 9 x 3.14
Area = 254.34 sq. inches
Answer:
Number is 4
Step-by-step explanation:
.03n = 1
n = 1/.03
.12 x (1/.03) = 4
The planes will pass each other in 1.14 hours.
Why?
To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.
The speed will be:
Now, calculating the time, we have:
Hence, the planes will pass each other in 1.14 hours.
Have a nice day!
Answer:
35
Step-by-step explanation:
Let number = x
(1/5 of x) + (3 * x) = 42 + (2 * x)
x/5 + 3x = 42 + 2x
1/5x + 3x - 2x = 42
1 1/5x = 42
6/5 x = 42
x = 42 ÷ 6/5
x = 42 * 5/6
x = 210 / 6
x = 35
The number is 35
