A lid has a diameter of 8 inches. What is the area of the lid?

1 answer:

4 0

Answer: Ok So If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.

The formula for working out the circumference of a circle is:

Circumference of circle = π x Diameter of circle

This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."

PLease solve down beow

saul85 [17]

$-58+2\left(h-29\right)-h=41$

$-58+2(h-29)-h+58=41+58$

$2(h-29)-h=99$

$h-58=99$

$h-58+58=99+58$

$h=157$

Hope this helps!

Thanks!

1. To solve this problem you must apply the following proccedure:

2. You have to verify if secx sinx=tanx, so, you have:

3. You know that secx=1/cosx, and tanx=sinx/cosx, therefore:

(secx)(sinx)

(1/cosx)(sinx)

sinx/cosx
