Answer:
41.89
explanation:
the formula for finding the volume of a cone would be pi x r^2 x h/3;
3.14 x 4 x 3.33333333, which equals 41.89.
hope that helps :)
If the number is 5 or greater you round it up
if its four or less you round down
Answer:
Step-by-step explanation:
2. area of a triangle is 1/2 b h
1/2 (5 * 2) = 5 yd squared
area of the circle is pi r squared
you only need 1/2 of this area
find all these areas and add them together.
6. this is just a square sitting on a rectangle.
36 x 36 for the square
36 x 60 for the rectangle
add these together.
8. this a 1/2 circle and a triangle.
area of a circle is pi r squared
r is 7 in this problem
the area of a triangle is 1/2 b h
height is 7x2 here or 14
add the two together.
