If the baseball radius is 1.4 inches what is the circumfrance in inches

8.8 in

Step-by-step explanation:

To find a circumference you need the diameter. To find the diameter you multiply the radius x2.

1.4x2=2.8

Tp get the circumference you multiply the diameter by pi or 3.14

The formula is d

so you multiply 2.8 by pi which is=8.79645943005 or to the nearest hundredth=8.8

31.4 in³

Step-by-step explanation:

The box is just big enough to hold the 3 balls, so it must have a length 6 times the radius of each ball, a width 2 times the radius, and a height 2 times the radius.

The volume of the box is:

V = (6r)(2r)(2r)

V = 24r³

The volume of the 3 balls is:

V = 3 (4/3 π r³)

V = 4πr³

So the volume of the air is:

V = 24r³ − 4πr³

V = (24 − 4π) r³

Since r = 1.4 inches:

V = (24 − 4π) (1.4 in)³

V ≈ 31.4 in³

Explanation:

Given:

the time for which the ball travels:

Angular speed of the ball:

Now the tangential speed at the equator of the ball:

(the tangential speed due to rotation and the linear speed are having the same direction)

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The total nom of  code that can be used is equal to 5+3 = 8

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
