FIND THE SURFACE AREA OF THE FOLLOWING SHAPES! Round to the nearest tenth IF NECESSARY!

1.

2.

3.

4.

Step-by-step explanation:

1. Find the area of the base. 10×10=100. Now, find the area of one of the triangles. 5×13=65. Multiply 65 by 4. Now, add this number to 100. 100+260=

2. Divide the diameter by 2 to get the radius. r=12. h=10. . . . . . . . .

3. . r=4. h=12.6. . . . . . . .

4. Find the area of the base. 9×4=36. Multiply this by two to get the base and the top. This is 72. Now, find the front side area. 9×3=27. Multiply this by two to get the front and back sides. This is 54. Now, find the area of the left side face. 4×3=12. Multiply this by 2 to get both sides. This is 24. Add 72+54+24=

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
