Answer:

87.92 in.

Step-by-step explanation:

The formula for circumference of a circle is: πd (diameter) or 2πr(radius).

π - pi

Here, only the radius (14) is shown. So we would have to use this formula: 2πr.

Now, let's just plug-in the numbers.

**3.14 is commonly used for pi.**

2πr

2 × 3.14 × 14 = 87.92

We could simply double the radius, and use this formula instead: πd

πd

3.14 x 28 = 87.92

As you can see, I got the same answer either way.

Therefore, the circumference of this circle is 87.92 in.

If $120.99 is charged for 654 units of electricity

pochemuha

Answer:

The cost of one unit of electricity is $0.185

Step-by-step explanation:

Amount charged = $120.99

Units of electricity used = 654

The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.

So that,

cost of one unit of electricity = $\frac{120.99}{654}$

= 0.185

cost of one unit of electricity = $0.185

This implies that the cost of electricity used is charged at $0.185 per unit.

Thus for 654 units of electricity used, the cost would be;

654 x $0.185 = $120.99

Tema [17]

9514 1404 393

Answer:

yes

Step-by-step explanation:

You can go at this a couple of ways:

1. The total length David needs is (1.75 m) × 4 = 7.00 m. His 7.28 m piece is long enough to provide the pieces he needs.

2. The length of each piece when the wood is cut into quarters is ...

(7.28 m)/4 = 1.82 m

This is longer than the 1.75 m needed, so each piece is long enough.
