\large\begin{gathered} {\underline{\boxed{ \rm {\purple{Formula \:  \:  Using \:  =   \: 4 \: \pi \:  {r}^{2} }}}}}\end{gathered}

  • r represents the radius of sphere.

\bf \ \implies \: \: r \:  =  \:  \frac{Diameter}{2}  \\

\bf \ \implies \: \: r \:  =  \:  \frac{14}{2} \\

\bf \ \implies \: \: r \:  =  \:   \cancel\frac{14}{2} \:   \:  \large ^{7}  \:  \\

\bf \ \implies \: \: r \:  =  \:  7 \: cm

<h3>Substuting the values in formula </h3>

\bf \large \longrightarrow \: \: 4 \: \pi \:  {r}^{2}

\bf \large \longrightarrow \: \: 4 \:  \times  \: \pi \:  \times  {7} \: ^{2}

\bf \large \longrightarrow \: \: 4 \:  \times  \: \pi \:  \times  49

\bf \large \longrightarrow \: \: 196 \: \pi \:  {cm}^{2}

Hence , the surface area of sphere is 196 π cm²

Answer: 196πcm²

Given

Diameter = 14

Radius = d/2

= 14/2

= 7

Surface area = 4πr²

Take π = 22/7

= 4×22/7×7×7

= 616 cm²

Susan owns a home that is worth $128,318.74, a 2005 truck worth $10,615.00, and has investments that total $4,459.16. Susan owes
allochka39001 [22]

Answer:

Net worth is defined as:

Assets - Liabilities.

Assets are what you own.

Liabilities are what you have to pay.

So, home + truck + investments are assets.

Likewise, mortgage + student loans + credit cards are liabilities.

Doing the math, Susan's net worth is

Assets - Liabilities

$143,392.90 - $98,077.12 =

$45,315.78

Susan's net worth is $45,315.78

Good luck!
