6+n less than or equal to sign 2n-1
Answer:
340.8cm^2
Step-by-step explanation:
So surface area is basically the area of all the sides combined. And we know that the area of a triangle is 1/2bh, and for a rectangle it is LW. So there are three congruent rectangles, and one of those rectangle's area is 72 ( 6 x 12), so you can multiply that by 3 to find all three rectangles, which is 216. We also know that the two triangles are congruent. and the base is 12, and height is 10.4, so 12 x 10.4 is 124.8.
We take the total of the rectangles and the triangles to find the total surface area:
216 + 124.8 = 340.8cm^2
Answer: ?
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
Basically when the equation is adding you subtract from each side of the equation....
So:
x + 40 = 75
-40 = -40
75 - 40 = 26
x = 26
Answer:
Step-by-step explanation:
The diameter of the circle is the distance from the endpoint to another endpoint. The diameter of the given circle is segment PQ. To determine the diameter of the circle, we would apply the formula for determining the distance between two points on a straight line is expressed as
Distance = √(x2 - x1)² + (y2 - y1)²
Therefore,
Diameter = √(1 - - 3)² + (9 - 5)²
Diameter = √4² + 4² = √32
Radius = diameter/2 = √32/2
A circle is the set of all points in a plane equidistant from a fixed point called the origin or center.
The center of the circle is determined by applying the midpoint formula
(x1 + x2)/2, (y1 + y2)/2
= (- 3 + 1)/2, (5 + 9)/2
Center = (- 1, 7)
The formula for determining the equation of a circle us expressed as
(x - h)² + (y - k)² = r²
Where
r represents the radius of the circle
h and k represents the x and y coordinates of the center of the circle. Comparing with the given points,
h = - 1 and k = 7
Substituting into the formula, it becomes
(x - h)² + (y - k)² = r²
(x - - 1)² + (y - 7)² = (√32/2)²
(x + 1)² + (y - 7)² = 32/4
(x + 1)² + (y - 7)² = 8
