Answer:
200.96
Step-by-step explanation:
Area is
Where r is the radius, we can find the radius since the radius is half of the diameter. Since the diameter is 16, the radius is 8. Now let plug it in the equation.
Which equals
Use 3.14 as pi then multiply
Which is 200.96
Answer:
$50
Step-by-step explanation:
3/5=30/x
x= The total cost
You can see that 3×10 multiplies to 30, so the total cost would be 5×10.
Total cost= 50

hi i dont understan hahahag
Answer:
10
Step-by-step explanation:
Standard form for a circle is
(x - h)² + (y - k)² = r²
where (h, k) is the center and r is the radius
--------------------------------
x² + y² - 18x + 24y = -200
Rearrange
(x² - 18x) + (y² + 24y) = -200
Complete the square for x
(x - 9)² + (y² + 24y) = -200 + (-9)²
Complete the sqaure for y
(x - 9)² + (y + 12)² = -200 + (-9)² + 12²
(x - 9)² + (y + 12)² = 25
Now the equation is in standard form
r² = 25
r = 5
Therefor Diameter = 10
