Please help, im literally so lost

Helen [10]

Answer:

RP = 2.3

PQ = 1.0

RQ = 2.3

Step-by-step explanation:

The pictures says RP = RQ,

so:

3x - 0.4 = x + 1.4

this you can simplify to:

x = 0.9

Then fill x in:

RP = 3*0.9 - 0.4 = 2.3

PQ = 0.9 + 0.1 = 1.0

RQ = 2.3

The area of the circle above is 314 units2. What is the circumference of the circle? use 3.14

aleksandrvk [35]

Answer:

$r =\sqrt{\frac{314 units^2}{3.14}} = 10 units$

And the circumference is given by this formula:

$C = 2\pi r$

And replacing the value fo r we got:

$C = 2\pi *10 units = 62.8 units$

And then the final answer would be 62.8 units for the circumference.

Step-by-step explanation:

For this case we know that the area for a circle is given by:

$A = \pi r^2$

And we know that $A = 314 units^2$

We can find the radius from the previous formula like this:

$r^2 = \frac{A}{\pi}$

$r^2 = \frac{314 units^2}{\pi}$

$r =\sqrt{\frac{314 units^2}{3.14}} = 10 units$

And the circumference is given by this formula:

$C = 2\pi r$

And replacing the value fo r we got:

$C = 2\pi *10 units = 62.8 units$

And then the final answer would be 62.8 units for the circumference.
