Answer:

$37.84625

Step-by-step explanation:

(5.79*2)+9.25+2.29+12.50=35.62

tax: 6.25% of total cost:

6.25/100 * 35.62=2.22625

total cost + tax

35.62+2.22625=37.84625

Answer: I think its $37.84625 according to the working shown :)

Step-by-step explanation:

cost of paper= $5.79, hence 2 is 2 x 5.79= 11.58

pens= $9.25

paperclips= $2.29

calendar= $12.50

Total= 11.58+9.25+2.29+12.50= 35.62

6.25% sales tax on total purchase= 6.25/100 x 35.62= $2.22625

Adding the sales tax: 35.62+2.22625‬= $37.84625‬‬

arlik [135]

The height of the cone is inches, if the cylinder and cone have the same volume.The cylinder has a radius of 2 inches and a height of 3 inches. The cone has a radius of 3 inches.

Step-by-step explanation:

The given is,

A cylinder and a cone have the same volume

Cylinder has a radius 2 inches and height of 3 inches.

Cone has a radius of 3 inches

Step:1

For Cylinder'

Formula to calculate the volume of cylinder is,

$V = \pi r^{2} h$ ..................................................(1)

where,

r - 2 inches

h - 3 inches

From the equation (1)

= $\pi$ × $2^{2}$ × 3

= 37.70

V = 37.70 cubic inches

Step:2

For cone,

Formula to calculate the volume of cone is,

$V = \pi r^{2} \frac{h}{3}$ ..................................................(2)

From the statement,

cylinder and a cone have the same volume

$V_{cylinder}$ = $V_{cone}$

37.70 = $\pi$ × $3^{2}$ × $\frac{h}{3}$

37.70 = 9.42478 × h

Height of the cone, h = 4 inches

Result:

Thus the height of the cone is 4 inches, if a cylinder and cone have the same volume.The cylinder has a radius of 2 inches and a height of 3 inches. The cone has a radius of 3 inches.
