Answer:
Equation of circle:
(x-10)² + (y+8)² = 36
Step-by-step explanation:
Given that,
Center of the circle is (10, -8)
and diameter = 12
We know that radius is half of the diameter.
So, radius (r) = 
= 6
Now we have standard form of circle :
(x - h)² + (y - k)² = r²
Where (h,k) is the center of circle and r is the radius.
Now put the value of h, k and r in circle's equation
h =10
k = -8
r = 6
Equation of circle:
(x-10)² + (y+8)² = 36
That's the final answer.
I hope it will help you.
Answer:
11 11/18
Step-by-step explanation:
Calculate by breaking to wholes and parts
Answer:
B
Step-by-step explanation:
The volume (V) of the prism is calculate as
V = lbh ( l is the length, b the width and h the height )
l = h = 4 × 
= 
b = 3 × = 1, thus
V = × 1 × = 
ft³
Answer:
447 cm or 337 cm can be both
If sum of numbers (a) +(b) is 1419 and
(a) and (b) are <span>neighbors , whe have:
a + b = 1419 and b-a = 1;
<=> </span>a + b = 1419 and <span>a = b-1 ;
so we have b-1 + b = 1419 <=> 2b = 1420 <=> b=710 and a = 709
Answer: 710 and 709
