Solve the formula C = πd for d

REY [17]

Answer:

$d = \frac{C}{\pi}$

Step-by-step explanation:

$C= \pi d\\$

Isolate d ; Divide both sides of the equation by $\pi$

$\frac{C}{\pi} = \frac{\pi d}{\pi }$

Simplify

$\frac{C}{\pi} = d\\\\d = \frac{C}{\pi}$

Note; Another formula for d(diameter) =

In isosceles pqr with base , pq = 2x + 3, and pr = 9x - 11. what is the value of x?

Anon25 [30]

First, draw and label a rough sketch of an isosceles triangle. Now put in the values of pq=2x+3 and pr=9x-11

You know that the triangle is isosceles, therefore, the sides pq and pr are identical.

Now, make the equations equal to each other to find the value of x.

2x+3=9x-11
3+11=9x-2x
14=7x
14/7=x
2=x

Therefore the value of x=2.

Hope I helped :)
