A cylinder vessels of diameter 1.4 metre holds 770 litre of water . calculate the height of The vessel please help me
tomorrow there is my math exam

D=1.4 m

Volume= 770 litres of water

V= pi × r^2 × h

770=1.53 × h

h= 503

Step-by-step explanation:

Diameter d= 1.4m

Radius r= 1.4/2 =0.7m

volume of cylinder = 770/1000 = 0.77 m³

that is,

πr²h = 0.77

3.14*0.7²*h=0.77

3.14*0.49h = 0.77

1.54h=0.77

h=0.77/1.54

h =0.5

Hence height of the cylinder is 0.5 m

(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
