The diameter of a circle refers to a straight line passing from side to side through the center connecting to points in the circumference.
In the other hand the radius is a line passing through the center of the circle to the circumference, and it is the half of the measure of the diameter.

On this question is given that the diameter of a circle is 2 yards and it is asked to find the radius.

Radius=1/2diameter
Radius=1/2(2)
Radius=1

The radius of a the circle is 1 yard.

The circle's radius is 1 yard. You take half of the diameter to get this value.

$\frac{7}{15} + \frac{1}{3} + \frac{3}{5} = \frac{7}{15} + \frac{5}{15} + \frac{9}{15} = \frac{21}{15} = \frac{7}{5} = 1.4$

Answer:

$4,080grams$

Step-by-step explanation:

the formula for density is:

$d=\frac{m}{V}$

where d is density, m is mass, and V is volume.

solving for m in the last equation:

$m=d*V$

so if we find the volume and multiply it by the density $d=8.3gr/cm^3$ we will get the mass of the object.

The volume of a rectangular prism is given by:

$V=l*w*h$

where $l$ is length, $w$ is width and $h$ is height:

$l=5in\\w=3in\\h=2in$

we substitute to find the volume:

$V=5in*3in*2in\\V=30in^3$

since the density has units of $cm^3$ we need the volume also in units of $cm^3$ , so we make the conversion using:

$1in^3=16.3871cm^3$

multiplying by 30:

$30in^3=491.612cm^3$

and now we find the mass with the equation:

$m=d*V$

substituting d and V:

$m=(8.3gr/cm^3)(491.612cm^2)\\m=4,080.36gr$

the nearest gram is: $4,080grams$
