Question

Hi I am having trouble with solving and finding the answers to this problem Find the perimeter of the figure. Use 3.14 for ππ and round to at least 1 decimal place.

Answer 1

Given:-

An reatacngle with a half sphere at one side.

To find:-

The perimeter of the given image.

Now we are going to find the perimeter of the half sphere. The formula to find half sphere is,

`\pi r+d`

Where r is radius and d is diameter.

The radius of the sphere is 2.5 and the diameter is 5. Substituing the values we get,

`\begin{gathered} \pi r+d=3.14*2.5+5 \\ \text{ =12.85} \\ \text{ =12.9} \end{gathered}`

Now we find the perimeter of the rectangle below. we get,

`5+5+5=15_{}`

Now to get the total perimeter we need to add both the values. so we get,

`12.9+15=27.9`

So the required perimeter is 27.9
