The true statements are that the diameter is 5 in, the base area is 19.63 in², the volume is 58.88in³ and the cost is $14.72.
Since the radius is 2.5 in, the diameter is 2*2.5 = 5.
The base is a circle. Therefore the base area is found by the formula
A=πr²=(3.14)(2.5)²=19.625≈19.63in².
The volume of a cone is given by multiplying the base area by the height and then taking 1/3 of it:
19.625(9)/3 = 58.875≈58.88in³.
The cost would be 58.88*0.25 = $14.72.
"Matt is correct because he multiplied the exponents."
Because negative times negative is equals to positive
The answer is 2.4 there you goo my good sir
Answer:
=12y+18
Step-by-step explanation:
=(3)(6+4y)
=(3)(6)+(3)(4y)
=18+12y
=12y+18
