Acylinder has a base with a radius of 3 cm and a height of 12 cm. what is the volume of the cylinder? (use π = 3.14.) a. 452.16 cm3 b. 1356.48cm3 c. 339.12 cm3 d. 113.04 cm3

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

13664

step-by-step explanation:

=cross multiply

=100 x = 13664

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
