Answer:

83.75 cubic inches

Step-by-step explanation:

We are given the diameter of a cone 8 inches, and height 5 inches and we are to find the volume of this cone.

(diameter is 8 inches so radius will be 4 inch)

We know that the volume of a cone is given by:

Volume of cone = $\pi r ^ 2 \frac { h } { 3 }$

Substituting the given values in the above formula:

Volume of cone = $\pi \times 4 ^ 2 \times \frac { 5 } { 3 }$ = 83.75 cubic inches

(diameter is 8 inches so radius will be 4 inches)

three friends earned more than $200 washing cars. they paid there parents $28 for supplies and divided the rest of money equally

makvit [3.9K]

So
x=earned
x>200
they paid their parrents 28 for supplies (this assumes that they paied 28 altogether and not 28 each)
so subtract 28 from pay
new pay=y
y>200-28
y>172
divided it among themselves (3)
172/3=57 and 1/3=57.33
they each earned more that $57.33

Answer:

The answer is A, (1,2).

Step-by-step explanation:

Hope this helps!

8x-4(x+1) = 0

x =1

y = 1 + 1

y = 2

(x,y) = (1,2)

2 = 1 + 1

8 x 1 - 4 x 2 = 0

Simplify

2 = 2

0 = 0

Solution = (1 , 2)
