Answer:
Volume = V=  346.43 cm ^3 
Step-by-step explanation:
15.32 x 10 = 153.2cm Area of side
We find the height of the cylinder, to enable the radius/2 for the circle side x 2
it would be the same as triangle side 6 but the exact circumference is worked out at 6.37
We start by finding the side
As a = half circumference = 20 x sin (30) =10 we x2 for full circumference, then divide by pi
10 +10 =20cm  circumference.
20/6.28 =3.1847133758 = radius
we x 2 and find the height
 3.1847133758 x 2  = 6.3694267516
rounded to nearest 10th = 6.4 units exact 6.37
We find other measurements before calculating volume.
and b =  √400-√100 = √300
b= 17.32 (height for volume use) or length of right side cylinder
c= 20 hypotenuse.
Volume = πr2h
V= 3.14 * 6.37 * 17.32 =346.43
V=  346.43 cm ^3 
V= 346 cm ^3 to nearest 10th
V= 346.43 cm^3

Step-by-step explanation:
<u>Step 1: Define</u>
-6(t + 2) = 18
<u>Step 2: Solve for </u><em><u>t</u></em>
- [Distributive Property] Distribute -6:                                                             -6t - 12 = 18
- [Addition Property of Equality] Add 12 on both sides:                                 -6t = 30
- [Division Property of Equality] Divide -6 on both sides:                                t = -5
