Answer:

5mm

Step-by-step explanation:

using the formula of volume of cone i.e. 1/3 ×πr²h

1/3 × πr²h = 314

or, r²= (314×3)/ (π×h)

or, r² = 25

r= 5 mm

Simplify the following expression. (4x − 8)(4x + 8)

vitfil [10]

Answer:

16x^2 - 64

Step-by-step explanation:

(4x − 8)(4x + 8)

We recognize that this is the difference of squares

(a-b) (a+b) = a^2 - b^2

=(4x)^2 - 8^2

=16x^2 - 64

(2y+1.6)/0.8=30/2.5<br> Please Help!<br> Solve for Y

galina1969 [7]

y = 4

first note that the right side simplifies to 12, equation can be written

$\frac{2y+1.6}{0.8}$ = 12 ( multiply both sides by 0.8 )

2y + 1.6 = 9.6 ( subtract 1.6 from both sides )

2y = 8 ( divide both sides by 2 )

y = 4
