Use the following net to find the surface area of the solid figure it represents.

hodyreva [135]

Answer:

The solid formed is a cylinder

The total surface area is $131.88cm^2$

Step-by-step explanation:

The given net is made up of a rectangle and two circles.

The total surface area is the area of the rectangle plus the area of the two circles.

This implies that:

$S.A=75.36+2(28.26)$

$\implies S.A=75.36+56.52$

$\implies S.A=131.88cm^2$

The rectangular surface can be folded into the curved surface of a cylinder with the two circles becoming the lid.

Find the length of the unknown side

wel

If leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)

Convert the general form of the circle given into standard form.

Semmy [17]

$The\ standard\ form\ of\ the\ circle:\\\\(x-a)^2+(y-b)^2=r^2\\\\where\\(a;\ b)\ are\ the\ coordinates\ of\ a\ center\ of\ the\ circle\\r\ is\ a\ radius\ of\ the\ circle\\------------------------$

$2x^2+2y^2-20x-8y+50=0\ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2+y^2-10x-4y+25=0\\\\x^2-10x+y^2-4y=-25\\\\x^2-2x\cdot5+y^2-2y\cdot2=-25\\\\\underbrace{x^2-2x\cdot5+5^2}_{(*)}-5^2+\underbrace{y^2-2y\cdot2+2^2}_{(*)}-2^2=-25\\(x-5)^2-25+(y-2)^2-4=-25\\\\(x-5)^2+(y-2)^2-29=-25\\\\(x-5)^2+(y-2)^2=-25+29$

$\boxed{(x-5)^2+(y-2)^2=4}\\\\the\ center:(5;\ 2)\\the\ radius:r=\sqrt4=2$

$(*)\ (a-b)^2=a^2-2ab+b^2$

Find a point- slope form for the line with slope 1/5 and passing through the point (-4,-6)

weeeeeb [17]

Answer: y-(-6)=1/5(X-(-4))

Step-by-step explanation:

to put together a point slope expresion the equation would be y-y1=m(x-x1)

y1 and x1 being the points on the line and (m) being the slope
