Can someone please help me with this question the instructions are to use a calculator to find the perimeter (the solid lines and curves) of each figure. The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable. Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.

The answer is 113.04(inch)

Step-by-step explanation:

2r=24(inch)

r=12(inch)

A circle perimeter 2r*pi .

A  semicircle perimeter is (2r*pi)/2= r*pi.

3 semicircle perimeter are 3*r*pi = 3*12*3.14=113.04(inch)

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

mean, 40.6
