Answer:

As Per Provided Information

We have to use π = 3.14

Diameter of baseball is 3 inch

So, Radius of Baseball will be

  • Radius = Diameter/2

Radius = 3/2 inch

Radius = 1.5 inch

we have been asked to determine the surface area of given baseball .

<u>Using </u><u>Formulae </u>

<u>\boxed {\bf  \: Surface \:  Area_{(Baseball)} \:  = 4 \pi {r}^{2} }</u>

substituting the value and let's solve it

\longrightarrow\tt  \:Surface  \: Area_{(Baseball)} \:  = 4 \times 3.14 \times  {1.5}^{2}  \\  \\  \\ \longrightarrow\tt  \:Surface  \: Area_{(Baseball)} \:  = \: 4 \times 3.14 \times 2.25 \\  \\  \\ \longrightarrow\tt  \:Surface  \: Area_{(Baseball)} \:  = \: 12.56 \times 2.25 \\  \\  \\ \longrightarrow\tt  \:Surface  \: Area_{(Baseball)} \:  = \: 28.26 \:  {inch}^{2}

<u>Therefore</u><u>,</u>

  • <u>Surface</u><u> </u><u>Area </u><u>of</u><u> </u><u>baseball</u><u> </u><u>is </u><u>2</u><u>8</u><u>.</u><u>2</u><u>6</u><u> </u><u> </u><u>sq.</u><u> </u><u>inch</u><u> </u><u>.</u>

So, your answer is 28.26 sq.in

TSplit  into prime factors

1080  = 2*2*2*3*3*3*5

Its not a cube because  although there are  2 triplicates there is also a 5.
