Il y a quelques années, aux États-Unis, on a établi un nouveau record en faisant éclater 10 000 L de grains de mais pour produire 222 m
de mais soufflé.
A une autre échelle, les
formats de maïs soufflé offerts
au cinéma sont eux aussi
gigantesques. Par exemple,
voici le développement d'un
contenant de maïs soufflé
e petit format »
9 cm
Quelles seraient les dimensions
d'un contenant semblable à
ce petit format » qui pourrait
tout juste contenir la quantité
de maïs soufflé qui constitue
le record des États-Unis ?
27 cm
18 cm​

Alcoa was $10.02 a share yesterday. today it is at $9.75 a share. if you own 50 shares, did ou have capital gain or loss ? how much of a gain or loss did you have ? express the capital gain/loss as a percent of the original price

Astudent showed the steps below while solving the inequality |x-4|< 1 by graphing.

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
