Answer:

408.2sq inches

Step-by-step explanation:

Area of the cylindrical box = 2πr(r+h)

r is the radius  = diameter/2

r = 10/2 = 5in

h is the height = 8in

Substitute

Area of the cylindrical box  = 2(3.14)(5)(5+8)

Area of the cylindrical box = 2 * 3.14 * 5 * 13

Area of the cylindrical box  = 408.2sq inches

Write an equation for the sentence below. Then solve the equation.
Romashka-Z-Leto [24]
The answer is D thirteen multiplied by h is 13h. The word "is" typically means = so 13h=104. to solve for this you want to isolate the h on one side of the equation. to do this we need to get rid of the 13 and move it on the other side of the equation. the new equation is h=104÷13. So, h=8. Hope this helps!

Sarah and Bryan went shopping and spent a total of $47.50 Bry an spent $15.50 less than what Sarah spent how much did bryan spen
Bogdan [553]
Since Bryan spent $15.50 less than Sarah, you would start by dividing the total amount they spent together in half.

$47.50 ÷ 2 = $23.75

Then you would take Bryan's 1/2 of the total and subtract $15.50.

$23.75 - $15.50 = $8.25

So, it looks like Bryan spent $8.25.

Check step:

If you add it all back together:

Sarah + Sarah Bryan = Total
$23.75 + $15.50 + $8.25 = $47.50

The sum of two numbers is
bekas [8.4K]
Okay you have 2 sum unknow lets call them X+Y

so X+Y=33, 4X=108

Get X by it self then plug it in 4X=108

X=-Y+33
4(-y+33)= 108
-4y+132=108 Then subtract the 132
-4y=-24 Y=6 then to find X subtract 33-6=27
Y=6 X=27 if you check it works out
