In the fist you have to know: any angle opposite the head is equal in measurement.
so now we know one angle in the triangle it is 82
All corners of the triangle are equal 180
so we have to do this 180-82=98
so we have to collection (4x+8)+(8x-6)=98
12x+2=98
12x=96
x=8
4(8)+8=40
the answer is 40

A right circular cylinder has a height of 2214 ft and a diameter 225 times its height.

Temka [501]

Answer:

Volume is 431288166770775 cubic feet.

Step-by-step explanation:

The height of the cylinder = 2214 ft

Let d be the diameter . Hence, we have

d = 225 × 2214 = 498150 ft

Hence, the radius should be half of diameter.

$r=\frac{d}{2}\\\\r=\frac{498150}{2}\\\\r=249075ft$

The volume of cylinder is given by

$V=\pi r^2h\\\\V=3.14(249075)^2(2214)\\\\V=431288166770775ft^3$

HELPPPPPPPPPPPPPPPPPPP!!!

Angelina_Jolie [31]

Answer:

15.13cm

Step-by-step explanation:

From that above question:

We are told that:

Lateral surface area of a right circular cone : πr√r² + h²

We are give the following parameters:

Lateral surface area = 236.64cm²

Radius = 4.75cm

We are to find the height

Making h the subject of the formula

h = √[(A/r)² - πr²]/π

h = √[(236.64/4.75)²- π ×4.75²]/π

h = 15.12975 cm

Approximately to the nearest hundredth = 15.13cm
