A basketball has a diameter of 9.5cm.

Which of the expressions shows how to determine the volume of air the basketball can hold?

A
34π(4.75)3

B
34π(9.5)3

C
43π(4.75)3

D
43π(

Answers

Answer:

C. $(4)/(3)\pi\cdot(4.75)^3\ cm^3$

Step-by-step explanation:

The volume of the ball with radius R can be calculated using formula

$V=(4)/(3)\pi R^3$

A basketball has a diameter of 9.5 cm, so its radius is

$R=(D)/(2)=(9.5)/(2)=4.75\ cm$

Hence, the volume of air the basketball can hold is

$V=(4)/(3)\pi\cdot(4.75)^3\ cm^3$

Ralph is 3 times as old as Sara in 4 years, Ralph will be only twice as old as Sara will be then. Find Ralphi's age now

Answers

Answer:

Step-by-step explanation: Let x represents Sara's age, since Ralph is 3 times as old, the Ralph's age will be 3x.

In 4 years time, Sara will be x+ 4 , Ralph will also be 3x + 4

It was said that Ralph will be as twice as Sara's age in 4 years

⇒ 3x + 4 = 2 ( x+4)

⇒ 3x + 4 = 2x + 8

collecting the like terms

3x - 2x = 8 - 4

x = 4

Since x represents Sara's age, then Sara is 4 years and since Ralph is presently 3 times Sara's age, then Ralph's age is 3 x 4 = 12 years
