How do you find the value of x for this figure?
Studentka2010 [4]
The 2 lines intersect, and by definition it will create equal opposite angles.  Since we know that the angle created is 125 degrees, then the angle on the opposite side also must equal 125 degrees.  But wait, they broke up the angle into 2 angles made up of a 64 degree angle and an X degree angle.  These 2 angles must add up to 125 degrees.

x + 64 = 125
x = 125 - 64
x = 61 degrees

The radius of a circle is 4 m. Find its area in terms of <br> π<br> π.
wlad13 [49]

Answer:

16π

Step-by-step explanation:

Given:

\text{Radius of circle}: 4 \ \text{m}

<u>Formula:</u>

\text{Area of circle} = \pi r^{2}

Replace the radius in the formula:

\implies \text{Area of circle} = \pi (4)^{2}

Evaluate the area:

\implies \text{Area of circle} = \pi (4)(4)

\implies \text{Area of circle} = 16\pi

Since the question says to determine the area in terms of π, the final answer is 16π.
