Answer:
the formula for the volume of a cone is:
1/3hπr²
1/3×12m×π×8m=100.48m³
Answer:
30 degrees
90 degrees
60 degrees
Step-by-step explanation:
If two of the sides are four, we know that the triangle is a right triangle so one angle is 90 degrees. if the other angle is 30, you can add them. 30+90=120. Then subtract it by 180 because all angles in a triangle add up to 180. 180-120=60.
For perimeter you will add each side together so
8ft+22ft+12ft+16ft=58
So your perimeter is 58ft.
For area your going to divide the shape into 2 to get the area as this is an irregular shape, so
Base 1+base2x height / by 2
22+8 x4/2
30x4/2
120/2
60
If you’re wondering how I got 4 I subtracted 16 with 12 to know what the height was. Good luck!!
Plug it in.
A being the coefficient of the first term, B the coefficient of the second, and C the coefficient of the third. . .
e.g.: 4x^2 + 7x - 8
a = 4, b = 7, c = -8
