Answer:

Are the pencils side by side or are they 2 x 2?

If they are side by side, then the band like a rectangle

but two of the sides are rounded.

In that case, The length is 10x 4 = 40.

The width is a half circle with diameter 10, which has

a circumference (perimeter) of 1/2*PI*10 = 5 * pi.

The total length of the band is 2*40 + 2*5*pi = 80 + 10*pi

A basketball team wants to paint half of a free-throw circle grey. If the radius of the free-throw circle is 5.4 feet, what is t

FromTheMoon [43]

Answer:

The area which would be painted grey will be "47.7812 ft²".

Step-by-step explanation:

The given values are:

Radius of circle, r = 5.4 feet

Value of pi, π = 3.14

As we know,

Area of Semicircle = $\frac{\pi r^2}{2}$

On putting the values in the above formula, we get

= $\frac{3.14\times (5.4)^{2}}{2}$

= $\frac{3.14\times 29.26}{2}$

= $\frac{91.5624}{2}$

= $45.7812 \ ft^2$

Write the inequality for the graph

Svetach [21]

Answer:

x≤-2

Step-by-step explanation:

it would be that because if the graph is going to the left that means it is less than x and the opposite is for greater than. Now if there is a closed circle that means the sign is equal to hence the line under the sign. So therefore it's x≤-2
