The diameter of a marble is 3/2 of an inch.How many marbles are needed to make a row of marbles 9 inches long?

6 marbles. Since they stand right next to each other, the length is going to be (# of marbles) * (diameter) = 9.\n\nIf i understand the question correctly.

3 feet is 36 inches.\n\n0.8 feet is 8/10 of a foot. Solve 8/10 = x/12 for x, and you get 9.6 inches.\n\nSo 3.8 feet is 36 + 9.6 inches, or 45.6 inches.

Yuri has a 98 inch board\nYour probably learning guess and check, so i'll make this as easy as possible.\n0 inches longer is 49 inches each. If you add 1 inch to one side, and take one away from the other, you get 50 and 48, do it again you get 51 and 47. Repeat until you get a difference of 10, which is 44 inches and 54 inches

draw a big circle...\ncut a piece of string that stretches across the circle, this is the diameter...\ncut another, and one more...got 3?\nglue them to the outside of the circle...\ndoes it enclose the circle?...do ya need more string???\nthats why pi (not pie) is 3.14......

9 inches * 7 inches = 63 square inches (c)

the shorter piece is 2 feet long and the longer one is 6 feet long\n\n8/4 = 2\n\n2*3 = 6 \n\n6 + 2 = 8

Area of a circle = pi * r^2\n= pi * 118^2  <--take half of 236 mm to find the radius\n= 43744 mm^2\n\nArea of a square = s^2\n43744 = s^2\ns = 209 mm\n\nSo your square has to have sides of 209 mm if it will have the same area as the circle above.

Its length?\n\n9 inches baby.\n\n;)

area = pi times the radius squared\n\nThe diameter is twice the radius.\n\nSo divide the diameter in two, square that and multiply by pi.

radius= diameter/2\narea=(pi)(radius)^2\n\narea of an 18 inch pizza= (pi)(9)^2= 81(pi)\narea of a 14 inch pizza= (pi)(7)^2= 49(pi)\n\ndifference= 81pi-49pi= 32pi= 100.5 square inches

1 mil = 1/1000 of an inch.\n\n12 mils = 0.012 inches.

The trick is turning the word problem into equations.\n(Key: length = l; width = w)\n\nThey tell you the length is 3 feet more than twice the width, so:\nl = 2w + 3\n\nThen they tell you the perimeter (which is twice the width and twice the length) is 36, so:\n2l + 2w = 36\n\nYou should be able to take it from there.

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

5 cm  at 1 m/s\n\narea first, then volume, then per second.\n\narea = PI r2 \n\n2.5 cm squared * 3.141592 =  19.63495 sq cm\n\n19.63495 sq cm * 1 meter.\n\n.1963495 cubic meter per second
