1188 = π<em>r</em>²<em>h</em>

For the formula to solve for <em>h, </em>you have to change the equation to:

<em>h </em>= 1188/π<em>r</em>²

which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.

because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)

Since you don't know the radius, you can't simplify this equation.

The answer is <em>h </em>= 1188/π<em>r</em>²

Your teacher spent 55$ on tulips and daffodils. a pot of tulips cost 5$ and a pot of daffodils cost 4$. if your teacher bought 1
Mama L [17]
7 tulips and 5 daffodils. An easy way to work this out is to list the multiples of both 5 and 4 until you get up to 55. Then you can find one number from each list which would add up to 55( which in this case would be 35 and 20) 35 being 7th in the 5 times table and 20 being 5th in the 4 times table.

Carol bought a coloring book. It is 11 inches long and 8 inches wide. What is the diagonal length of the book?
Leokris [45]

Answer:

13.6 inches

Step-by-step explanation:

We can use Pythagorean theorem: c=\sqrt{a^{2} +b^{2} }

Let c be the diagonal length, a for length, and b for width.

Substitute the values.

c=\sqrt{11^{2}+8^{2}  }

c=13.6 inches
