-12
Step-by-step explanation:
Answer:
surface area we can also take it as total surface area
9 is the radius and 5cm is the height . as they asked total surface area we have to take the area of base so tht we can make it as
total surface area = csa of cylinder + area of base
we know that,
2pirh+pir²
pir(2h+r)
pir(2×5+9)
pir(10+9)
pir(19)
22/7×9×19
3762/7
=> 537.42 cm² is the answer.

SO YOU HAVE X(-14X+9). ALL YOU DO IS THE DISTRIBUTION PROPERY OR MULIPLE BY X
SO WE GET -14X^2+9X.
X(-14X+9)= -14X(*)X+9(*)X= -14X^2+9X
HOPE THIS HELPS
Answer: The answer would be B
Step-by-step explanation:
The reason for this is because the triangles are similar they are also congruent. df=bc, fe=ac, ed=ab.
Because de=ba and ba=4 in. that would mean that de would also be 4in.
