Answer:828.96m^2
Step-by-step explanation:
radius(r)=8m
L=25m
π=3.14
total surface area of cone(tsa)=πxr^2+πxrxL
Tsa=3.14x8^2+3.14x8x25
Tsa=3.14x8x8+3.14x8x25
Tsa=200.96 + 628
Tsa=828.96
Answer:
Step-by-step explanation:
Let the numbers be x and y. Then we got following equations:
- x + y = 34
- 1/2x + 1/3y = 14
<u>Double the second equation and subtract from the first one. Solve for y:</u>
- x + y - x - 2/3y = 34 - 2*14
- 1/3y = 6
- y = 3*6
- y = 18
<u>Find x:</u>
X^2 x 8x -3x^2 +5 x 8x -5 x 3
8x^3 -3x^2 +40x -15
