For this case what you need to know is that the formula for the total surface area of a straight cone is
S.A = πrl + π r ^ 2
Substituting the values we have:
S.A = (3.14) * (7.9) * (3.7) + (3.14) * (7.9) ^ 2
S.A = 287.7496 cm ^ 2
Answer:
the surface area of a cone is
D) 288 cm ^ 2
Answer:
2.5
Step-by-step explanation:
youll have to multiply 4 times 5/8
Answer:
-ln|x−5| + 2 ln(x²+4) + 3 tan⁻¹(x/2) + C
Step-by-step explanation:
The fraction will be split into a sum of two other fractions.
The first fraction will have a denominator of x − 5. The numerator will the a polynomial of one less order, in this case, a constant A.
The second fraction will have a denominator of x² + 4. The numerator will be Bx + C.

Combine the two fractions back into one using the common denominator.

This numerator will equal the original numerator.

Match the coefficients.

Solve the system of equations.

So we can rewrite the integral as:

Solving:




Answer:
22
Step-by-step explanation:
20% * 40 = 20 / 100 * 40 = 800 / 100 = 8
1/4 * 40 = 40 / 4 = 10
So far we have use 8 + 10 = 18
There are 40 - 18 pages left
articles = 22
Answer:
x=5
y=2
Step-by-step explanation:
5x + 3y= 31
-6x - 3y = -36 (multiple by -3)
-x=-5
x=5
2(5)+y=12 or 25 + 3y= 31
10+y=12 3y=6
y=2 y=2
