Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal.

The arc length of the semicircle is or

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

where

D is the diameter of the semicircle

we have

substitute

----> exact value

Assume

----> approximate value

therefore

The arc length of the semicircle is or

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
