Find the smallest solution to the equation 2/3 x^2 =24

lesya692 [45]

Answer:

\frac{2x^2}{3} =24

Step-by-step explanation:

times both sides by 3

2x²=72

divide both sides by 2

x²=36

sqrt both sides

x=+/-6

x=-6 or 6

-6<6 so -6 is the smallest solution

Answer:

$B_2=4\pi r^2$

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

$B=\pi r^{2}$

where

r is the radius of the circular base

If the radius is doubled

then

$r=2r$

The new base area is

$B_2=\pi (2r)^{2}$

$B_2=4\pi r^2$

$B_2=4B$

therefore

The new area of the base is 4 times the area of the original base
