What is the volume of a cylinder with height of 7 feet and a base diameter of 18 feet

1780.38 cubic feet

Step-by-step explanation:

Diameter=18

π=3.14

Height(h)=7 feet

Radius(r)=18 ➗ 2=9

Volume=π x r^2 x h

Volume=3.14 x 9^2 x 7

Volume=3.14 x 9 x 9 x 7

Volume=1780.38

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
