P URGENT I've got a timer going on but really need your help to answer this thank you!!
astraxan [27]

Given:

The radius of inner circle = 13 yd.

The width of the shaded region = 8 yd

To find the area of the shaded region.

Now,

The radius of the outer circle = 13+8 yd = 21 yd

Formula

The area of a circle of radius r unit is \pi r^{2} sq unit.

A = A_{1}-A_{2}

where, A = The area of the shaded region

A_{1} = Area of the outer region

A_{2}= Area of the inner region

Now,

A_{1}= \pi (21^{2})

A_{1} = (3.14)(21)(21)

A_{1}= 1384.74 sq yd

And,

A_{2} = \pi (13^{2})

A_{2} = (3.14)(13)(13)

A_{2}= 530.66 sq yd

Therefore,

A = 1384.74-530.66 sq yd

A = 854.08 sq yd

Hence,

The area of the shaded region 854.08 sq yd.

A cylinder has a radius of 5x + 4 and a height of 2x + 5. Which polynomial in standard form best describes the total volume of t
Nana76 [90]

Answer:

Step-by-step explanation:

Volume = pi·(r^2)*h

r = radius = (5x+4)

h = height = (2x+5)

 

Volume = pi·(r^2)

Volume = pi·(5x+4)^2*(2x+8)

Volume = pi·(25x^2+40x+16)*(2x+8)

Volume = pi·(50x^2+80x+32+200x^2+32x+128)

Volume = pi·(250x^2+112x+160)
