Answer:

CSA of cylinder = 704cm²

We know that

CSA of cylinder = 2πrh

or 2πrh = 704

or, 2*22/7 *8 *h = 704 ( since r=8cm)

or, 352h = 704*7

or, h = 4928/352 = 14cm

Find an equation with a solution of

zaharov [31]

Answer: (x+5)(x-3)2 = 0

Step-by-step explanation: To write this equation as a polynomial, you must multiply it out.

begin by squaring the binomial, and remember to express this as a trinomial (middle term will be -6x).

Then, to finish the job, multiply that trinomial by the factor x+5. Hope this will help you.

50 POINTS + BRAINLIEST TO CORRECT ANSWER!! TRIG/GEO

WINSTONCH [101]

Option C:

We can find the value of PR using law of cosines.

Solution:

Given data:

∠Q = 18°, r = 9.5, p = 6.0

To find which length could be find in the triangle:

Law of cosines:

$a^{2}=b^{2}+c^{2}-2 b c \cos A$

Substitute a = q, b = r, c = p and A = Q

$q^{2}=r^{2}+p^{2}-2 r p \cos Q$

If we substitute the values given, we can find q.

q = PR

$PR^{2}=r^{2}+p^{2}-2 r p \cos Q$

Hence we can find the value of PR using law of cosines.

Option C is the correct answer.
