Answer:

Step-by-step explanation:

around the tank = 12 * circumference

circumference = d $\pi$

c = 30 $\pi$

c = 94.2477796

area around tank = 12 * 94.2477796 = 1130.973355

now top of tank

area of a circle = $\pi$ $r^{2}$

$\pi$ * $15^{2}$ = 706.858347

add the two surface areas together for the total

706.858347 + 1130.973355 = 1837.832

total surface area = 1837.8 $ft^{2}$

10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is

$\pi$ * $3^{2}$ * 10 = 282.7 $ft^{2}$

CosX sec^2X tanX - cosX tan^3X = sinX

ch4aika [34]

$\cos x\sec^2x\tan x-\cos x\tan^3x=\cos x\tan x\left(\sec^2x-\tan^2x\right)=\sin x\left(\sec^2x-(\sec^2x-1)\right)=\sin x$

What is 2/3 + 3/4 I don’t understand it at all

victus00 [196]

Answer:

6/12 or half

Step-by-step explanation:

this would be the answer because the lowest common denominator of 4 and 3 is 12 so you'd multiply them you'd get 12 then multiply 2 and 3 and get six therfore the answer is 6/12 or 1/2
