-3(b-4) = -2b
-3b + 12 = -2b
-3b + 3b + 12 = -2b + 3b
12 = b
Answer:
volume = (1/3)(area of base)(height)
area of base = pi * radius2 = pi * (10/2)2 = pi * 52 = 25pi cm2
volume = (1/3)( 25pi )( 9 ) cm3
volume = 75pi cm3
volume ≈ 236 cm3
<h2>plz give me brainliest :)) !!!!</h2>
Area of a circle can be calculated using the following formula
Area = πr²
where π = 3.14 and r - radius of circle
Area of the whole circle is for a central angle of 360°.
We are asked to find the area of a sector. Sector is when 2 arms enclose a central angle by which one arm has rotated.
1 radian = 57.3°
2.4 radian = 57.3 x 2 = 137.52°
Area for 360° = πr²
area for 137.52° = πr² / 360° x 137.52 = π x 6 cm x 6 cm x 0.382 = 13.752 cm²
200 Is 100 times as much as 2,
<em>200 / 2 = 100</em>
