Answer:
2 pieces of 3/8 yard.
Step-by-step explanation:
They tell us that originally the fabric measures 3/4 of a yard and then it is cut and remains pieces of 3/8 of a yard, so we must know how many pieces could have been cut so that they will be this size, therefore we must divide:
3/4 / (3/8) = 2
Which means there are 2 pieces of 3/8 yard.
18. 3 (-5 + 1) = 6 x -3 = -18 false its -14
19. 1/2 x 2 + 1/4 x 12 = 8 false its 4
Answer:
r= 16ft
Step-by-step explanation:
Answer:
Step-by-step explanation:
3x^2 - 5x + 12 - (5x^2 + x - 11) =
3x^2 - 5x + 12 - 5x^2 - x + 11 =
-2x^2 - 6x + 23 <====

Total surface area of cone is 176π
<h3>Explanation:</h3>
Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.
Hence surface area of curved surface of a cone is π×8×14=112π .
As surface area of base is π×82=64π .
Hence total surface area is 112π+64π=176π
