A classroom has 4 new boxes of chalk and 6 individual pieces of chalk in use. How many total pieces of chalk are in the classroo

AveGali [126]

The total number of pieces of chalk in the classroom will be the number of pieces in the 4 boxes in addition to the six individual pieces.

The average box of chalk holds 12 pieces of chalk
This means that 4 boxes have 12*4 = 48 pieces

Total number of pieces = 48 + 6 = 54 pieces of chalk

1. What is the area of a circle with a diameter of 12.6 in.?

Rudik [331]

Answer:

Part 1) $A=124.63\ in^{2}$

Part 2) Option b

Part 3) As n increases, ns get closer to $2\pi r$

Part 4) Option c $16\pi\ ft^{2}$

Part 5) Option b. $12.25\pi\ m^{2}$

Step-by-step explanation:

Part 1) What is the area of a circle with a diameter of 12.6 in.?

we know that

the area of a circle is equal to

$A=\pi r^{2}$

we have

$r=12.6/2=6.3\ in$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(6.3^{2})=124.63\ in^{2}$

Part 2) Which explanation can be used to derive the formula for the circumference of a circle?

First find the relationship of the circumference to its diameter by finding that the length of the diameter wraps around the length of the circumference approximately π times.

Use this relationship to write an equation showing the ratio of circumference to diameter equaling π

so

$\frac{C}{D}=\pi$
