Ineed the answer and how you did it

1.) 196.48 ft^2. 2.) 128 in^2. 3.) 41 cm^2. 4.) There are no dimensions for this problem. 5.) 63 m^2 6.) 104 yd^2.

Step-by-step explanation:

1. Use the area of circle formula and divide it by 2 to find the area of the hemisphere: pi*r^2. 3.14*8^2=64*3.14=200.96/2=100.48 Then multiply 8*12 to find the area of the rectangle. 8*12=96. Then Add the two values: 100.48+96=196.48. So the answer is 196.48 ft^2

2. Subtract 19 from 13 to get the height of the triangle, then multiply that by 8*1/2 which is 6*8*1/2=24. Then multiply 13*8=104 and add it to 24 to get 128. So the answer is 128 in^2.

3. Multiply 5*5 and 4*4 then add them together. 25+16=41. So the answer is 41 cm^2.

5. Subtract 7 from 11 to get the height of the triangle, the multiply it by 1/2*7 to get 4*7*1/2=14 The do 7*7 to get 49 and add it to 14. So the answer is 63 m^2.

6. The part you sectioned made a square(6 x 6) and a rectangle (6*12). So adding these two areas, 6*6=36, and 12*6=72, 36+76=104 So the answer is 104 yd^2.

Hope this helps! :P
