Answer:
28.26
Step-by-step explanation:
The question gives the first three digits of π, which is 3.14, and it gives us the radius, which is 3. So, just substitute them into the formula and you’ll get 3.14(3^2). Solve it and the final answer is 28.26.
Hope this helps! :)
To tell whether r = 2 is a solution of the inequality, substitute 2 for r and see whether the inequality produces a true or a false statement.
(2) + 4 > 8, add 2 and 4.
6 > 8, this is a false statement, because 6 is not greater than 8, so the value r = 2 is not a solution of the inequality r + 4 > 8.
Create an equation from the word problem. 'of' indicates multiplication, 'decreased' indicates subtraction, 'increased' indicates addition. Let's use 'x' for the number.
Now solve for 'x'. Subtract 3/10x to both sides:
Add 13 to both sides:
Divide 4/10 to both sides or multiply by its reciprocal, 10/4:
Hence, the distance between (7,8) and (-8,0) is:17
explanation: (a,b)=(7,8) and (c,d)=(-8,0)
