Answer:

≈ 1.3 inches

Step-by-step explanation:

Given that:

  • Sphere A = 30 cubic inches
  • Sphere B = 10 cubic inches

As we know, the formula to find the volume of a sphere is;

V = π\frac{4}{3} r^{3}

So we have:

  • Sphere A = 30 cubic inches

<=> π\frac{4}{3} r^{3}  = 30

<=>r^{3}  = 90/4π

<=> r ≈ 4.13

  • Sphere B = 10 cubic inches

<=> π\frac{4}{3} r^{3}  = 10

<=> r^{3} = 30/4π  

<=>  r ≈ 2.86

So the  different between the radius of sphere A and B is:

= 4.13 - 2.86

= 1.27

≈ 1.3 inches

A bike store sells scooters at a 54% markup. If the store bought each scooter for $29.25, what is the resale price to the neares
7nadin3 [17]

The purchasing price of the store = $29.25.

They want to resale it at 54% markup of the purchasing price.

54% of 29.25 = 0.54 × 29.25.

On multiplying 0.54 and 29.25, we get 15.795.

Resale price = The purchasing price + Markup

                      = 29.25 + 15.795.

On adding 29.25 and 15.795, we get 45.045.

We can round it to 45 to the nearest dollar.

<h3>Therefore, the resale price to the nearest dollar is $45.</h3>
