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)

At the end of year 1, Boller Co. had an ending balance in allowance for uncollectible accounts of $30,000. During year 2, Boller
Masja [62]

Answer:

$34,000

Step-by-step explanation:

First they had 30,000

Then wrote off 40,000

So balance is 30,000 - 40,000 = -10,000

Now, they want 8% of 300,000 as uncollectible. So that would be

0.08 * 300,000 = 24,000

Thus, to bring the balance to 24,000 [balance is -10,000], how much would they need to add?? Let it be x:

-10,000 + x = 24,000

x = 24,000 + 10,000 = $34,000
