Answer:

            \bold{h=\dfrac{S-2\pi r^2}{2\pi r}=\dfrac{S}{2\pi r}-r}

Step-by-step explanation:

\bold{S=2\pi r^2+2\pi rh}\\\\\bold{2\pi r^2+2\pi rh\ =\ S}\\\\{}\qquad -2\pi r^2\quad\ \ -2\pi r^2\\\\{}\quad \bold{2\pi rh\ =\ S-2\pi r^2}\\\\\div(2\pi r)\quad\ \div(2\pi r)\\\\\bold{h=\dfrac{S-2\pi r^2}{2\pi r}=\dfrac{S}{2\pi r}-r}

Regina has started making baby quilts to sell at a craft fair. The inside of each quilt will measure four feet by five feet and
Bezzdna [24]
Given are the statements describing the area of the baby quilts:

Inside dimensions = 4 x 5 feet
Border with uniform width = x feet
Total area of the quilt = 30 square feet

A = length x width

Area of inside quilt = 4 x 5
Area of quilt including the border = (4+2x) * (5+2x)

Therefore, the equations that are applicable are:

<span>2: (4+2x)(5+2x)=30
</span><span>4: 4x^2 +18x+20=30</span>
