((I've used 3.14 as pi))

Diameter = circumference / pi
= 4.5 / 3.14
= 1.43

Radius = diameter / 2
= 1.43 / 2
= 0.72

V = pi * r^2 * h
= 3.14 * 0.72^2 * 13
= 21.17
= B

Answer:

result is 20%

Step-by-step explanation:

initially B was 100%

therefore 100% - 40%

=60% remaining

60% - 40%

= 20%

Ryan wants to use the Fermi process to estimate the number of basketballs that would fill a gymnasium. As part of the process, h

Westkost [7]

A basketball is the shape of a sphere.

The volume of a sphere is given by

$V= \frac{4}{3} \pi r^3$

Given that the diameter of the basketball is 10 in., thus the radius is 10 / 2 = 5 in.

Thus, the volume of the basketball is given by

$V= \frac{4}{3} \pi(5)^3 \\ \\ = \frac{4\times125}{3} \pi=523.6\ in^3$

Therefore, The best approximate of the volume of the basketball is $5\times10^2\ in^3$

Rachel Plant has $28,000 invested in stock A and stock B. Stock A currently sells for $20 a share and stock B sells for $80 a

Wewaii [24]

Answer:

A= 66.6667

B = 333.3333

Step-by-step explanation:

Initial value of A = $20

Initial value of B = $80

Initial total=$ 28000

A moves up 50%= 20+(0.5*20)

A moves up 50% = 20+10

A moves up 50% =$ 30

B double it values = $80*2

B double it values = $160

Now total value is = $54000

A20+B80= 28000... equation 1

A30+B160= 54000.... equation 2

Multiplying equation 1 * 2

Multiplying equation 2 * 1

A40 +B160 = 56000

A30+B160= 54000

A30 = 2000

A= 2000/30

A= 200/3

A= 66.6667

A20+B80= 28000

Substituting A

200/3 (20) +B80= 28000

B80= 28000-4000/3

B80= 80000/3

B= 80000/240

B = 333.3333
