I might be able to help except I've no idea what the question is cos the web link is either wrong or just doesn't work. Try putting the question up like you did with you other ones where it's a picture. Then I can have a look and see if I can help you or not

**Surface Area of a Cylinder**

**I assume: https://vle.mathswatch.co.uk/images/questions/question18838.png**

\(\begin{array}{|rcll|} \hline \text{area} &=& 2\pi r^2+2\pi r h \quad | \quad r=6\ \text{cm},\ h=25\ \text{cm} \\ \text{area} &=& 2\pi 6^2+2\pi *2*25 \\ \text{area} &=& 2\pi *36+2\pi *50 \\ \text{area} &=& 72\pi +100\pi \\ \text{area} &=& 172\pi \\ \text{area} &=& 540.353936417 \ \text{cm}^2 \\ \hline \end{array}\)

Surface Area of a Cylinder is \(\mathbf{\approx 540.4\ \text{cm}^2}\)
