Answer: $1296
Step-by-step explanation:
Surface area of s sphere = 4πx r^2
Diameter = 1/2 radius
Surface area = 4π x 12^2
= 1809.56 cm^2 = 18.096 m^2
Material required = 71.62 x 18.096
= $1296
Answer:
$13
Step-by-step explanation:
First step is to convert cm to metres (24cm/100=0.24m)
therefore diameter is now 0.24
SA= 4π^r2 r=d/2=0.24m/2= 0.12m
SA= 4π^(0.12)^2= 0.1809...m^2
So since the surface area of this basketball is 0.1809..m^2, we then must calculate how much it will cost for the material to cover for one basketball. (this is why converting is important because you can end up with the wrong price/answer)
$71.62/1m^2 =0.1809..m^2 =$12.96
They want it in nearest DOLLAR so final answer is $13 to make one basketball
