$Volume \\ =π {r}^{2} h \\ =π· {3}^{2} ·8 \\ ≈226.19$

$surface \: \: \: area = 2πrh+2π {r}^{2} \\ =2·π·3·8+2·π· {3}^{2} \\ ≈207.34$

AlexFokin [52]

Answer: (1) 13/20 (2) 8 (3) Yes. They are proportional

<u>Step-by-step explanation:</u>

(1) 13 students take the bus.

33 - 13 = 20 students do not take the bus

$\dfrac{\text{take the bus}}{\text{do not take the bus}}:\dfrac{13}{20}$

(2)

$\dfrac{2\ red}{3\ green}=\dfrac{x}{12\ green}\\\\\\\underline{\text{cross multiply}:}\\2(12)=3(x)\\24=3x\\8=x$

(3)

$\dfrac{6}{10}\div \dfrac{2}{2}\quad =\dfrac{3}{5}\\\\\\\dfrac{9}{15}\div \dfrac{3}{3}\quad =\dfrac{3}{5}\\\\\\\dfrac{15}{25}\div \dfrac{5}{5}\quad =\dfrac{3}{5}$

All of the fractions simplify to the same number so they ARE proportional.

Answer:

140°

Step-by-step explanation:

$\because m\widehat{BG} = 360\degree - m\widehat{GCB} \\\therefore m\widehat{BG} = 360\degree - 300\degree \\\therefore m\widehat{BG} = 60\degree \\\because m\widehat{BGD} = m\widehat{BG} +m\widehat{GD}\\\therefore m\widehat{BGD} = 80\degree+60\degree\\\therefore m\widehat{BGD} = 140\degree\\\because m\angle BAD = m\widehat{BGD} \\\huge\purple {\boxed {\therefore m\angle BAD =140\degree}}$
