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.

Step-by-step explanation:

So you would have to find the circumference of a circle that is made of 2 of these semi circles. I'm sorry if that doesn't make sense.

1. The diameter is 34mm so using the given formula find the circumference.

2. multiply the perimeter of the semicircle by 5 and you should get your answer.

Hope this helps!

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
