find the surface area and volume of a basketball with radius equal to 29.5 inches if the basketball was filled with water how much water is needed

Radius of basketball r= 29.5in

Surface area of basketball S = 4π^2 

= 4×3.14×29.5^2 

= 870.25 in^2 

Volume of basketball V = (4 ⁄ 3) πr^3

= (4/3)×3.14×29.5^3

= 107481.67 in^3  

The quantity of water to full the basketball= volume of basketball = 107481.67 in^3

The answer is in the image 

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7
