The area of a circle is 153.86 square meters. What is the diameter of a circle?

7.8 (when I calculated I rounded to tenths so the actual answer might be a little bit different)

Step-by-step explanation:

the area of a circle is radius squared so

153.86= radius squared

sqaure root both sides and you get 12.4 =radius

divide both sides by pi and you get 3.9 which is the radius

the diameter is double the radius which is 3.9 *2 which is  7.8 :) hope this helped.

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
