The circumference<span> of a circle is the distance around the circle. </span>The circumference of a circle is calculated by the expression:

Circumference = 2πr

Circumference = 2π(30 inches)
Circumference = <span>94.2 inches
</span>
Therefore, the correct answer from the choices listed above is option C. Hope this answers the question.

Two functions are graphed on the coordinate plane.
rosijanka [135]

Answer:

Option B

Step-by-step explanation:

We can see that, from the picture provided, the graphs intersect at points( 0, 4 ) and ( - 4, 4 ), respective to functions f( x ) and g( x ). These intersection points makes each function equivalent to one another, and hence -

Function f( x ) where x = - 4 / Function g( x ) where x = - 4,

f( - 4 ) = 4,\\g( - 4 ) = 4\\----------\\f ( - 4 ) = g ( - 4 )

Respectively function f( x ) where x = 0 / Function g( x ) where x = 0,

f( 0 ) = 4,\\g( 0 ) = 4\\----------\\f ( 0 ) = g ( 0 )

<u><em>Your solution should be option b, "  f(-4) = g(-4) and f(0) = g(0) "</em></u>

A cylindrical basin is 2 feet tall and has a diameter of 5 feet, as shown. If the basin is completely filled with water, how muc
jarptica [38.1K]

Answer:

39.3 ft^3

Step-by-step explanation:

The cylindrical basin has a height of 2 ft and a diameter of 5 ft.

To find the amount of water that will completely fill up the basin, we simply need to find the volume of the basin.

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius of the basin (half the diameter) = 2.5 ft

h = height of the basin

Hence, the volume is:

V = \pi * 2.5^2 * 2

V = 39.27 ft^3 ≅ 39.3 ft^3

The cylindrical basin can hold up to 39.3 ft^3 of water.
