3 inches
Formula: Area of triangle= 1/2 * base * height Therefore 42 (area of triangle) = 1/2 * 6 (base) * height 42 = 3 * height 42/3 = (3 * height)/3 14 = height Therefore, the height of triangle is 14 inches
No, but an equilateral triangle is a regular polygon with 3 equal sides and 3 equal angles.
no
The formula for a triangle is (1/2)(base)(height). (1/2)(3)(2) = 3 square units.
Height of an equilateral triangle = √3/2 x side = √3/2 x 20 = 10√3 ≈ 17.32
Base x height x .50
Formula: Area of triangle= 1/2 * base * height Therefore 42 (area of triangle) = 1/2 * 6 (base) * height 42 = 3 * height 42/3 = (3 * height)/3 14 = height Therefore, the height of triangle is 14 inches
No, but an equilateral triangle is a regular polygon with 3 equal sides and 3 equal angles.
no
An isosceles triangle is not a regular polygon because it has only 2 equal sides but an equilateral triangle is a regular polygon because it has 3 equal sides and 3 equal angles.
The volume of a cylinder with a 9-inch height and a 3-inch radius is: 254.47 cubic inches.
No. A triangle with 2-inch sides is not congruent with a triangle with 3-inch sides.
Height of an equilateral triangle = √3/2 x side = √3/2 x 20 = 10√3 ≈ 17.32
The formula for a triangle is (1/2)(base)(height). (1/2)(3)(2) = 3 square units.
Easy. Since the side is the base and the apothem is the height of the triangle, multiply them and divide by two to get the area of the triangle. 3 * 3.46 = 10.38 /2 = 5.19. Then multiply by 6 to get the area of the hexagon. 5.19 * 6 = 31.14. You multiply by 6 because you can fit 6 regular triangles in a regular hexagon. We've already found the area of one regular triangle in the hexagon.
Since the area of a triangle is .5 x Base x Height, the area of this triangle would be: .5 x 2 x 3 = 3 So 3 units
An equilateral triangle is a regular shape because it has 3 equal sides.
