Answer:

4,116.9mm² (rounded up to nearest one decimal point)

Step-by-step explanation:

Diameter of a circle is 72.4mm (where mm stands for millimeters)

Area of a circle is given by πr²

Radius (r) = 72.4mm ÷ 2 = 36.2mm

Area = π × (36.2mm)² = 4,116.868677mm²

That is  4,116.9mm² (rounded up to one decimal point)

3 2 ? start fraction, 2, divided by, 3, end fraction of the doughnuts in a box have frosting. \dfrac12 2 1 ? start fraction, 1,
timurjin [86]

Answer:

\frac{1}{3} of the doughnuts in the box have frosting and sprinkles.

Step-by-step explanation:

If there are x doughnuts in the box. Then, \frac{2}{3} \times x = \frac{2x}{3}  of the doughnuts in the box have frosting. Therefore, \frac{1}{2} \times \frac{2x}{3} = \frac{1}{3}x of the doughnuts with frosting have sprinkles. This implies that \frac{1}{3} of the doughnuts in the box have frosting and sprinkles.

Under her cell phone plan, Sydney pays a flat cost of $35.50 per month and
Keith_Richards [23]

The number of gigabytes that Sydney can use while staying within her budget is less than 2.9 gigabytes.

<h3>What are gigabytes?</h3>

gigabytes (GB) – pronounced with two hard Gs – is a unit of storage capacity equal to approximately 1 billion bytes. In decimal form (base 10), a gigabyte is exactly one billion bytes. In binary form, a gigabyte is 230 bytes or 1,073,71,82 bytes. Giga comes from the Greek word for giant. Werner Buchholz is credited with coining the term byte in 1956 and helped design IBM's 7030 Stretch, the first transistorized supercomputer.

gigabytes has been a common unit of measurement for data storage products since the mid-1980s. In recent years, terabytes (TB) have become a more common measure of storage capacity, especially for hard drives and solid-state drives.

A. Find x. The figure is not drawn to scale.
Dovator [93]
As you can see in the graph, the arcs of arcQP + arcPR + arcQR = 360°, since they take up the whole circle.

therefore then 

\bf (8x-10)~~+~~(6x)~~+~~(10x+10)=360\implies 24x=360&#10;\\\\\\&#10;x=\cfrac{360}{24}\implies x=15\\\\&#10;-------------------------------\\\\&#10;\overline{QP}=8(15)-10\implies 120-10\implies \boxed{110}&#10;\\\\\\&#10;\overline{PR}=6(15)\implies \boxed{90}&#10;\\\\\\&#10;\overline{QR}=10(15)+10\implies 150+10\implies \boxed{160}

notice, all sides differ in length, thus the triangle is a scalene triangle.
