Please help ....this is due tomorrow
marshall27 [118]

A) 0.15 times $2,570 = $412.50

B) $122.85 times 2( 12 ) = $2,948.40

C) $2,570

D) All together it's  $2,948.40 + $2,570 = $5,518.40

For D I didn't add the down payment because it's not an additional charge.

I only did the first one because I don't know if you want me to finish the rest.

Hope I helped :)

A cone has a diameter of 18 units and height of 8 units. What is its volume?
m_a_m_a [10]

Answer:72

Step-by-step explanation:Given : A cone has a diameter of 18 units and height of 8 units.

We have to determine the volume of the given cone.

We know Volume of cone = 1/3\pi \\r^{2}h

Where r is radius of cone

h is the height  of cone

Given : diameter = 18units  so, radius is half of diameter = 9 units

height = 8 units

Substitute, we have,

Volume of cone = 1/3 n\\ (9^{2} ) 8

Simplify, we have,

Volume of cone = 72\pi

Thus, the volume of given cone is 72π cubic units.
