Answer:

b = 3

Step-by-step explanation:

the 2 indicated angles form a right angle and sum to 90° , that is

8b + 7 + 59 = 90

8b + 66 = 90 ( subtract 66 from both sides )

8b = 24 ( divide both sides by 8 )

b = 3

HELP MEEEE PLZ. i need to Find the surface area and volume

lisabon 2012 [21]

Answer:

A ≈ 494.80 $mm^{2}$

V = 827.02 $mm^{3}$

Step-by-step explanation:

height ( h ) = 13 mm

radius ( r ) = $\frac{9mm}{2}$ = 4.5 mm

Surface area = $2\pi rh + 2\pi r$

= 2π(4.5)(13) + 2π(4.5)

≈ 494.80 $mm^{2}$

Volume = $\pi r^{2} h$

= $\pi (4.5)^{2} (13)$

= 827.02 $mm^{3}$
