Answer:

The larger circle has an approximate area of 314 cm²

Step-by-step explanation:

As you can see by the diagram, the white circle is twice as wide as the grey circles.  That means that its radius is also twice theirs.

The grey circles have a radius of 5cm, so the larger has a radius of 10cm.

The radius of a circle is equal to πr², where r is the radius of the circle.  So the larger circle's radius is:

π × 10²

≈ 3.14 × 100

= 314.

So the larger circle has an approximate area of 314 cm²

What is the answer to the question?
Jobisdone [24]

Answer: C.

Step-by-step explanation:

An isosceles triangle is a type of triangle that has two identical sides and angle measures. Knowing that the two sides creating the 44 degree angle are equal, you can also know that both remaining angles are equal.

All three angles in a triangle must add to 180, so you can solve for f through this equation:

2f + 44 = 180

2f = 136

f = 68
