Answer:

1: 64π

2: 49π and 153.86

Step-by-step explanation:

For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)

To find the area of a circle use the following formula

π*r² where r is the radius

This means that the first answer is π*8^2

which is 64π

For the second one it's the same deal but the radius is 7

so the answer is 49π

<span>The easiest thing to do is convert all the measurements to yards...
18ft = 6 yards
6 inch = 1/6 yard ( 6 inches = 1/2 ft.... so 1/6 yard)
so the volume is V = 6 x 6 x 1/6
Then all you do is calculate the cost. I hope this helps you out</span>

Given:

The equation is

$\dfrac{1}{3}x=\dfrac{1}{5}$

To find:

The coefficient and reciprocal.

Solution:

We have,

$\dfrac{1}{3}x=\dfrac{1}{5}$

Here, $\dfrac{1}{3}$ is multiplied with x.

So, the coefficient of x is $\dfrac{1}{3}$ .

To find the reciprocal, we need to interchange numerator and denominator of a fraction.

So, the reciprocal of $\dfrac{1}{3}$ is $\dfrac{3}{1}=3$

Therefore, the reciprocal is 3.
