Approximately how much air would be needed to fill a soccer ball with a radius of 14 can ? Rounded too the nearest cubic centimeter

11494 cm³

Step-by-step explanation:

Taking the shape of ball as spherical (picture a rugby ball in this case), volume of a sphere is given by

V=(4/3)πr³

Where r is radius and v is volume.

Substituting 14 cm for r then

V=(4/3)π*14³=11494.0403219339 cm³

Rounded off, the volume is approximately 11494 cm³

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
