Ans: area = 33
Solution: (in the pic below)
X - the number of cats
The ratio of dogs to cats is 3:5, and there are 21 dogs.
![\frac{21}{x}=\frac{3}{5} \\ 3x=21 \times 5 \\ x=7 \times 5 \\ x=35](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7Bx%7D%3D%5Cfrac%7B3%7D%7B5%7D%20%5C%5C%0A3x%3D21%20%5Ctimes%205%20%5C%5C%0Ax%3D7%20%5Ctimes%205%20%5C%5C%0Ax%3D35)
There are 35 cats in the pet store.
(B) 16.5π
<u>Explanation:</u>
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²
![A = 2\pi r (h+r)\\\\A = 2 X \pi X 1.5 ( 4 + 1.5)\\\\A = 16.5\pi](https://tex.z-dn.net/?f=A%20%3D%202%5Cpi%20r%20%28h%2Br%29%5C%5C%5C%5CA%20%3D%202%20X%20%5Cpi%20%20X%201.5%20%28%204%20%2B%201.5%29%5C%5C%5C%5CA%20%3D%2016.5%5Cpi)
Therefore, the surface area would be 16.5π
