Answer:
7.1 (7.06 rounded to the tenth)
Step-by-step explanation:
The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is <em>half </em>of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
3. Do the calculation, and you should come out to get 7.06858347058
4. Round it!
Finding area for a circle is satisfying, isn't it? xD
Step-by-step explanation:

15 - c = 6
15 - 6 = c
9 = c
c = 9
Answer:
x = 5
Step-by-step explanation:
12x - 6 + 6 = 54 + 6
12x = 60
12/12 = 60/12
X = 5
When you use a tens fact you round to the nearest ten and 15-8=7. The nearest ten to seven is 10
Answer:10
Answer:
-4
Step-by-step explanation:
Slope = y2 - y1/x2 - x1
Given
x1 = 6
y1 = 2
x2 = 4
y2 = 10
Therefore
Slope = 10 - 2/4 - 6
= 8/-2
= -4
