Answer:
m<HGI=21°
Step-by-step explanation:
we know that
If GH bisects m<FGI then
m<FGH=m<HGI
substitute the values
(2x+1)°=(3x-9)°
solve for x
3x-2x=1+9
x=10°
The measure of angle HGI is equal to
(3x-9)° ------> substitute the value of x
3*10-9=21°
m<HGI=21°

The volume of the cone :V = 1/3 r² π hr = 9 cm, h = 6 cm and π = 3.14V = 1/3 · 9² · 3.14 · 6V = 81 · 3.14 · 2V = 508.86 ≈ 509Answer:C ) 509 cm³
Do you know how to find cubic metres??
The expanded notation method breaks a big number up into smaller numbers that're easier to work with. For example, for 82, you should first look at the 8, which is in the tens place (8 x 10), and then the 2, which is in the ones place (2 x 1). So together, 82 is ( (8 x 10) + (2 x 1) ), which equals (80 + 2). Now, you can multiply both 80 and 2 by 3: (80 x 3) + (2 x 3) = 240 + 6 = 246.
