Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = \frac{d}{2}

 = \frac{18}{2}

 = 9 \ cm

Height,

h = 20 cm

As we know,

⇒  Area of a cone = \frac{1}{3} \pi r^2 h

On substituting the given values in the above formula, we get

⇒                            = \frac{1}{3}\times 3.14\times (9)^2\times 20

⇒                            = \frac{1}{3}\times 3.14\times 81\times 20

⇒                            = 3.14\times 27\times 20

⇒                            = 1,695.6 \ cm^3

What is the length of MN
jek_recluse [69]

Answer:the length of segment MN is 12

Step-by-step explanation:

because the angles at the bottom of each segment are equal, the length of each segment is equal as well, so set you equation as 3x=x+8, subtract x from 3x then divide 8 by 2 which equals 4. (x=4) then plug in the value of x into x+8 and you have 12
