The right answer is Option C.

Step-by-step explanation:

Given,

Diameter = 6 cm

Radius = \frac{Diameter}{2}=\frac{6}{2}=3\ cm

Height = 8 cm

π = \frac{22}{7}

Surface area = 2πrh+2πr²

Surface area = 2*\frac{22}{7}*3*8+2*\frac{22}{7}*(3)^2\\

Surface area = \frac{1056}{7}+\frac{396}{7}=\frac{1056+396}{7}

Surface area = \frac{1452}{7}

Surface area = 207.4 cm²

Rounding off to nearest whole number

Surface area = 207 cm²

The surface area of cylinder is 207cm².

The right answer is Option C.

A swimming pool is 15 by 30 feet and a consistent 5 feet deep. you are painting the walls and floor of the pool. if a gallon can
lukranit [14]

the bottom of the pool is 15 x 30 = 450 sq feet.

 you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet

 then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet

 for a total of 450 +300 +150 = 900 square feet

 1 can covers 250 sq ft

so 900/250 = 3.6

 so you would need 4 cans of paint

Can someone please help on number 20? WILL MARK YOU AS BRAINIEST. (can you also show how you do the problem?) :(
PSYCHO15rus [73]

Answer:

x =(22-√196)/6=(11-7)/3= 1.333

Step-by-step explanation:

(3x2 -  22x) +  24  = 0

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -22x  its coefficient is  -22 .

The last term, "the constant", is  +24

Step-1 : Multiply the coefficient of the first term by the constant   3 • 24 = 72

Step-2 : Find two factors of  72  whose sum equals the coefficient of the middle term, which is   -22 .

     -72    +    -1    =    -73

     -36    +    -2    =    -38

     -24    +    -3    =    -27

     -18    +    -4    =    -22    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -18  and  -4

                    3x2 - 18x - 4x - 24

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3x • (x-6)

             Add up the last 2 terms, pulling out common factors :

                   4 • (x-6)

Step-5 : Add up the four terms of step 4 :

                   (3x-4)  •  (x-6)

            Which is the desired factorization

Equation at the end of step 2:

 (x - 6) • (3x - 4)  = 0

STEP 3:

Theory - Roots of a product

3.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

There are 59 people going on a field trip.
Maru [420]

You first multiply 6 and 8 to see how many people are put in the vans without rented a van. This would equal 48. You then subtract 48 from 59 to see how many people still need to be in a van. This would leave you with 11 people. Then you divide 8 from 11 to get 1 3/8. This means you need 2 vans to fit everyone.
