Dmitrij [34]

Answer:

  2. "two thirds of the fourth power of <em>r</em>"

  4.  n + 14

  6.  7 +11n

  8.  (2/5)n^2

__

  7.  28

  8.  1/5

Step-by-step explanation:

2. "two thirds of the fourth power of <em>r</em>"

__

4. "sum" means the listed items are added. You can use any convenient variable to represent "a number." I often use <em>n</em> for <em>n</em><em>umber</em>.

  n + 14

__

6. "7 more than" means 7 is added to whatever follows. "11 times a number" means the number is multiplied by 11.

  7 + 11n

__

8. "of" means "times". The square of a number is that number to the power of 2.

  (2/5)n^2

__

7 & 8 (evaluation). Your calculator can do this. (If not, get one that can.) Note that parentheses are needed around numerators and denominators and anything else that must be treated as a single value.

Help plz..And No links!! I repeat No links!!
Aleksandr [31]

Answer:

1193.2 sq. in.

Step-by-step explanation:

SA = LA + 2B    

where LA is the lateral area and B is the area of the base (circle)

B = πr^2 = 3.14(10)^2 = 3.14(100) = 314

Area of 2 Bases = 2 (314) = 628

LA = Ch    where C is the circumference of the base

LA = πdh = 3.14(20)(9) = 565.2

SA = 628 + 565.2 = 1193.2 sq. in.
