Side u = 8 units

Explanation:

(The triangle is a right triangle so we can use trigonometry to find u.)

(If you look from angle 45 degrees’ view: u is opposite, v is adjacent and 8 sqrt(2) is the hypotenuse because it is opposite to the right angle.)

sin = Opposite/Hypotenuse

sin(45) = u/[8 sqrt(2)]
sin(45) x 8 sqrt(2) = u
8 = u
u = 8 units

A box with a volume of 40 cubic inches holds 10 balls. A box with a volume of 60 cubic inches holds 15 of the same kinds of ball
lesya692 [45]
Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
m= \frac{60-40}{15-10} and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0.  The equation of the line then is y = 4x + 0 or just
y = 4x

Find the surface area S of the following cylinder.
Tanya [424]

Answer:

384π

Step-by-step explanation:

From the diagram,

Diameter ( d ) = 16

Height ( h ) = 16

To find : Surface area of Cylinder = ?

Radius ( r ) = ?

Formula : -

r = d / 2

r = 16 / 2

r = 8

Formula : -

Surface area of Cylinder = 2πr ( r + h )

Surface area of Cylinder = 2πr ( r + h )

= 2π x 8 ( 8 + 16 )

= 16π x 24

Surface area of Cylinder = 384π
