Find the surface area of a cylinder that has a raius of 13.5 cm., and a height of 90 cm. Show all work without using a calculato

professor190 [17]

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=13.5\\ h=90 \end{cases}\implies SA=2\pi (13.5)(90+13.5) \\\\\\ SA=27\pi (103.5)\implies SA=2794.5\pi \implies SA\approx 8779.18$

well, the last part will be with a calculator, but you can simply use the area in π terms.

PLEASEE HELPP MEE IN MATHH!!!! NUMBERS 6 AND 7!!!!

Tomtit [17]

Answer:

6.) angle 1 = 61 degrees. angle 2 = 61 degrees. . 7.) angle 1 = 44 degrees

angle 2 = 44 degrees

Step-by-step explanation:

main reason is that because of Alternate Interior angles theorem angle 1 = angle 2

for both questions 6 and 7.

Also the angles that form a straight line sum to 180 degrees

so 61 + 58 + 61 = 180

and for 7

90 = 46 + 44
