Okay so multiples of 3 on a 10 sided die is 3,6,and 9 so 3/10 times 
if your rolling it 250 times you cross multiply with x so the equation would be 3/10= x/250
do 3x250 which is 750 
750//10 is 75
x=75 so its your answer:)

The answer is option b.

<h2>144π</h2>

Step-by-step explanation:

Surface area of a sphere is 4πr²

where r is the radius

diameter = radius / 2

<h3><u>For Big </u><u>sph</u><u>ere</u></h3>

radius = 15 / 2 = 7.5in

Surface area = 4π(7.5)²

= 225π

<h3><u>Small </u><u>sph</u><u>ere</u></h3>

radius = 9/2 = 4.5in

Surface area = 4π(4.5)²

= 81π

Difference of the surface areas is

Surface area of big sphere - surface area of small sphere

Which is

225π - 81π

<h3>= 144π</h3>

Hope this helps you.

lubasha [3.4K]
Total Time = (M x K) / (M + K)
5 = (8 x K) / (8 + K)
40 + 5 K = 8K
40 = 3K
King can do the job in 13.33 Hours

King could mow (1 / 13.33) of the lawn in one hour.
