I am assuming this is for a circle??
Area for circle is pi*r^2
you didn't say what to use for pi so I will use 3.14
so area = 3.14 * 6^2
6^2 = 36
so 3.14*36 = 113.04 square feet. Round this answer off as needed.
Answer:
DC
Step-by-step explanation:
A radius is a line segment extending from the center of a circle to the circumference.
Answer:
$20196
Step-by-step explanation:
12 × 9 × 6 = 648 cubic feet ( volume of slab )
3 feet to a yard
So 648 ÷ 3 = 216
Multiply this by 1.1 to add an extra 10%
237.6 Cubic Yards Needed
$85 × 237.6 = $ 20196
Hope this helps
Answer:
Crafts books: 7
Cookbooks: 13
Step-by-step explanation:
Let x be the crafts book
Let y be the cookbooks
Solve for x:
- Plug x and y in: x + y = 20
- Re-write: y = x + 6
- Plug in x + 6 instead of y: x + x + 6 = 20
- Combine like terms: 2x + 6 = 20
- Subtract 6 from each side, so it now looks like this: 2x = 14
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7
Solve for y:
- Re-use an equation from above: y = x + 6
- Plug in the value of x: y = 7 + 6
- 7 + 6 = 13
- So, y = 13
I hope this helps!
It would be -4. subtracting a positive is the same as adding a negative
