The formula for the area of a triangle is A=12bh .

Find the area of a triangle with a base (b) of 7 feet and a height (h) of 12 feet.

The area of the triangle is square feet

42 square feet.

Step-by-step explanation:

1/2 times 12 times 7 is 42.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
