The formula for the volume of w sphere is v=4\3 r3 what is the formula solved for r?

Answers

V of w sphere = (4)/(3)\pir³
Multiply by 3 on either sides to get rid of the fraction.
V * 3 = (4)/(3) *3 \pi r^3
3V = 4\pir³
Now divide either sides by 4\pi to isolate r³
(3V)/(4 \pi ) = (4 \pi )/(4 \pi )r³
4\pi and 4\pi cancels out
(3V)/(4 \pi ) = r³
Take the cube root to isolate r.
\sqrt[3]{ (3V)/(4 \pi ) } = \sqrt[3]{r^3}
the cube root cancels the cube

\sqrt[3]{ (3V)/(4 \pi ) } = r

B1 of a trapezoid in which Area = (48x+68) inch squared, Height = 8 in, B2 = (9x + 12) in.what I have so far is

48x +68 = 8 (B1 + 9x +12)

what do I do from there????????????????? the question is asking to solve for Base 1/ B1

Answers

A=(1/2)(b1+b2)h =

=(48x+68)in² = (1/2)( b1+(9x+12))8

=b1= 3x+5

To fond the midpoint add each term to each other and divide by 2.

3+2 = 5

5/2


In 2-i, i can also be written as 1i


So now 8+1 = 9

9/2

The midpoint would be 5/2 + 9/2i
