​You need to wrap a present that you will put inside a cylindrical container. You’ll need to know how much will fit in the conta
nirvana33 [79]

Answer:

149.28 sq. inches

137.5 cubic inches.

Step-by-step explanation:

The cylindrical container has length or height (h) 7 inches and has a diameter of 5 inches i.e. radius (r) 2.5 inches.

Now, total surface area of the container = 2\pi r^{2} + 2\pi rh

= \frac{2 \times 22 \times (2.5)^{2} }{7} + \frac{2 \times 22 \times 2.5 \times 7}{7}

= 39.28 + 110  

= 149.28 sq. inches (Answer)

Again the volume of the container will be \pi r^{2}h

= \frac{22 \times (2.5)^{2} \times 7}{7}

= 137.5 cubic inches. (Answer)

17. Which of the following is a factor of both x^2 - x - 6 and x^2- 5x+6?
andreyandreev [35.5K]

Step-by-step explanation:

For the equation x^{2} - x - 6, factoring gives us the following:

(x - 3)(x + 2)

For the equation x^{2} - 5x + 6, factoring gives us the following:

(x - 3)(x - 2)

From this, we see that the common factor is (x - 3)
