Answer:
Step-by-step explanation:
Midpoint of the diameter is the center.
<u>Use midpoint formula to determine the coordinates:</u>
- x = (2 - 4)/2 = -1
- y = (5 + 13)/2 = 9
<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>
- r =
<u>Use the equation of the circle:</u>
- (x - (-1))² + (y - 9)² = 5²
- (x + 1)² + (y - 9)² = 25
Correct choice is 4
Answer:
The surface area is 22 square feet
Step-by-step explanation:
For a right rectangular prism, we have the formula for the area as;
A = 2(lb + lh + bh)
Accordingly, we have l as the length, b as the breadth and h as the height
Using the given dimensions, we have
A = 2(3(1) + 3(2) + 1(2))
A = 2(3 + 6 + 2)
A = 2(11) = 22 square feet
Yes, the perpendicular bisector DOES pass through the center.
Hope this helps :)
