Question

Mayank made a nice bird-bath for his garden in the shape of a cylinder with a hemispherical depresstion at one end. The height of the cylinder is 1.45m and its radius is 30cm. Find the total surface area of the bird bath.​

Answer 1

$\huge\star{\underline{\mathbb{\red{A}\pink{n}\green{s}\blue{w}\purple{e}\orange{r}}}}$

$\longrightarrow$$\sf\pink{TSA\:=\:CSA\:of\:cylinder\:+\:CSA\:of\:hemisphere}$

$\longrightarrow$$\sf\blue{2πrh\:+\:{2\pi \: r}^{2}\:=\:2πr(h+r)}$

$\longrightarrow$$\sf\green{2 \times \frac{22}{7} \times 30(145 + 30) {cm}^{2}}$

$\longrightarrow$$\sf\purple{{33000cm}^{2}}$

$\longrightarrow$$\sf\red{{3.3cm}^{2}}$
