4 angles = 360

120 + 117 +55 = 292

360-292 = 68

4th angle = 68 degrees

a glass cylinder has a diameter of 7 inches and a height of 1.5 inches. Glass had a density of 2.58 grams per cubic centimeter.
Anarel [89]

Answer:

The mass of the cylinder is 149\ g

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume is equal to

V=\pi r^{2} h

we have

r=7/2=3.5\ in ----> the radius is half the diameter

h=1.5\ in

assume

\pi=3.14

substitute

V=(3.14)(3.5)^{2}(1.5)

V=57.70\ in^{3}

step 2

Find the mass

we know that

The density is equal to the mass divided by the volume

D=m/V

Solve for the mass

m=D*V

substitute the values

m=(2.58)*(57.70)=149\ g

The retail price of a product is $77.30 per square metre. Trade price is retail less 12.5%. Calculate the trade price of 5.35m o
kipiarov [429]

Answer: $1935.56

Step-by-step explanation:

T.P=R.P-(12% of R.P)

R.P=$77.30 per 1m²

When m =5.35, m²=5.35²=28.6225

R.P= $(77.30×28.6225)

R.P=$2212.52

12.5% of R.P=0.125×$2212.52=$276.565

Therefore,

T.P = $2212.52-$276.565 = $1935.96

Note: T.P is Trade Price and R.P is Retail Price.

Hope this helps?
