The rectangle has an area of 9 because it is 3x3.

The circle has an area of pi because it is (pi)(r)(r).

You subtract to get 9-3.141592... to get 5.86

The circle has an area of pi because it is (pi)(r)(r).

You subtract to get 9-3.141592... to get 5.86

Wouldn't it be 24? Because the range is the max-minimum=range. So the equation is x-16=8, which is x=24

The volume of a similar cone would be 750. If you use proportions and put

16/x = 40/1875, you would cross multiply to get 40x=30000. Then, you would solve for x. X is equal to 750.

Increased price = $10 + $10×15% = $11.50

decreased price = $11.50 - $11.5×25% = 8.625

decreased price = $11.50 - $11.5×25% = 8.625

The surface area of a rectangular prism is:

A=2(xy+xz+yz), where x,y, and z are its dimensions...in this case:

A=2(120*110+120*4+110*4)

A=2(13200+480+440)

A=2(14120)

A=28240 mm^2

A=2(xy+xz+yz), where x,y, and z are its dimensions...in this case:

surface area is the area of all the faces on a shape so to speak.

2(120 x 110)=26,400

2(120 x 4)=960

2(110 x 4)=880

880+960+26,400=28,240

Surface area = 28,240

Point D is the midpoint of the outer circle that we aim to find the area of

The circle has a diameter of WZ and radii of WC and CZ

We know that YZ=YD=10 cm

Let DC be and CY be

The radius of the outer circle can be written as or which we can equate to find the value of

Therefore, the radius of the circle is

And hence the area of the circle is =324

Part1

there are 360° in a circle (clock), and thus if we check how many degrees in a clock with 60minutes, then it'd be 360/60, or 6° per minute

now, the clock went from 3:35 to 3:55, 20 minutes, how many degree is that? 6*20

The shaded region is the area of the circle minus the area

of the pentagon.

A circle = pi * r^2

A circle = pi * 15^2

A circle = 706.5 cm^2

A regular pentagon = (a * p)/2 where a is the apothem, p is the perimeter.

The apothem id the perpendicular height from the midpoint of a side to the center of the pentagon.

To find the apothem you have to use a trig ratio.

A pent = (8.3 * 12*5)/2

A pent = 249 cm^2

Shaded region: circle - pentagon 706.5 - 249 = 457.5

of the pentagon.
