Step-by-step explanation:
<u>Step 1: Define</u>
A = 2πrh + 2πr²
<u>Step 2: Solve for </u><em><u>h</u></em>
- [Subtraction Property of Equality] Subtract 2πr² on both sides: A - 2πr² = 2πrh
- [Division Property of Equality] Divide 2πr on both sides: (A - 2πr²)/(2πr) = h
- Rewrite/Rearrange: h = (A - 2πr²)/(2πr)
<em>Answer:</em>
<em>x=7</em>
<em>Step-by-step explanation:</em>
<em>6x+8+7x-9=90</em>
<em>13x+8-9=90</em>
<em>13x-1=90</em>
<em>add 1 to both sides</em>
<em>= 13x=91</em>
<em>divide both sides by 13</em>
<em>= x=7</em>
