What is the best approximation for the perimeter of a semicircle with a diameter of 64 meters?
Use 3.14 to approximate pi.

100.48m

164.48m

200.96m

264.96m

Correct option A) 100.48m .

Step-by-step explanation:

Here we have , Diameter of a semicircle is 64 meters . We need to find the perimeter of semicircle . Let's find out:

We know that perimeter of a circle = , where r is radius of circle .

⇒

⇒ , where D is diameter of a circle .

Since, a semicircle is half of a circle so Perimeter of semicircle will also be half of circle i.e.

⇒

⇒

Diameter = 64 meters

⇒

⇒

⇒

Therefore , Perimeter of semicircle is 100.48 m . Correct option A) 100.48m .

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
