A triangular pyramid has a base shaped like an equilateral triangle. The legs of the equilateral triangle are all 4 feet long, a
9966 [12]

Answer:

Total surface area of the pyramid =    25ft^{2}

Step-by-step explanation:

To find the surface area of the triangular- based pyramid, we will use the formula:

Surface area = Area of base + Area of the three faces

Area of base of the pyramid = Area of equilateral triangle = 0.5 \times base \times height

= 0.5 \times 4 \times 3.5= 7ft ^{2}

Area of the slant faces of the pyramid is 0.5 \times base \times slant height

0.5 \times 4 \times 3 = 6 ft^{2}

Since there are 3 slant surfaces the total surface area of the pyramid =7 + 3 \times (6)= 25ft^{2}

olga2289 [7]

Answer:

See answer and graph below

Step-by-step explanation:

∬Ry2x2+y2dA

=∫Ry.2x.2+y.2dA

=A(2y+4Ryx)+c

=∫Ry.2x.2+y.2dA

Integral of a constant ∫pdx=px

=(2x+2.2Ryx)A

=A(2y+4Ryx)

=A(2y+4Ryx)+c

The graph of y=A(2y+4Ryx)+c assuming A=1 and c=2
