The area of the regular hexagon is given by:\n\nA = 2.598 s^2\n\nSo if the sides are 12 inches each;\n\nA = 2.598 (12 in)^2\n\nA = 374 in^2

1 sq. inch = 0.0069444 sq. ft.   \nSo you multiply 363.9 x 0.0069444, and the total is 2.527 sq.ft

Area = length x width

it would be X<12, with extra line

Yiu would first decide how many decimal places you are going to consider.  The usual is 3.  Then work it from there...;

Hi. 0.754 x 1.0 would be obvious.  0.754 x .1 would involve moving the decimal point one place to the left.  0.754 x 0.8 would involve solving for the last value and adding 8 times.

3.14 inch !! Surprised No? Here is te answer, when we  tie apiece of string around the earth so that it touches all the way around means , we are calculating the circumference of the cross section of the earth.\n\nLet R be the radius of the cross section which is a circle, then coircumference will be\n\n2(Pie)R\n\nNow to get the string 1/2 an inch away from the surface, we need to increase the radius by 1/2 an inch, Thus the new circum ference will be\n\n2(pie) x(R+1/2)\n\n= 2(Pie)R + 2(Pie)/2\n\n=2(Pie) R + Pie\n\nDifference in the new circumference and old will be the difference in the length of the string which will be equal to\n\n2(Pie)R + Pie -2(Pie)R = Pie\n\n\nand value of Pie is 22/7 =3.14, Since we have taken inch as our Unit, Answer will be 3.14 inches more string would be required.

Here's an idea.  Show them something that's pretty much flat and rectangular, such as piece of stiff carpet or a pad of paper.  Write on the board what the perimeter, area, and volume are.  Have them measure it with a tape measure and come up with the answers that you have.  They'll see that they just have to add for the perimeter but multiply for the area and volume.

Assuming this means a circle...\n\ndefn/:\n\nc=circurmfernce\nA=area\nr=radius\nd=diameter\npi=pi (~3.1415926...)\nd=2*r\n\nC=2*pi*r=d*pi\nA=pi*(r^2)...(area is pi*r squared...pie are squared-no there not their round).\nA=pi*(d^2)/4.\n\njust plug and chug...\n\nC=10*pi.\nA=25*pi.\n\nanswer:\n\nit's that simple

The question is WRONG. If you have length =6 and width =7, P=26 and A=42.

yup your answers are correct.\n\nhowever your units are not, length and width are measured in yards not sq yards.

if you know radius, it is 2 time the radius times 3.14 (2*r*Pi), if you know diameter, its is diameter times 3.14 (d*Pi)

10.63. There are 2.54 cm per inch so 27/2.54 = 10.63

I'm not sure what you mean by "front end" rounding but if you mean to the nearest whole number, the first answer would be 29.  The second answer is 17.  Third one is 8.  The ratio is 360:4
