Answer:
1,092 cm²
Step-by-step explanation:
Smaller box:
Length = 24 cm
Wrapping paper = 936 cm²
Bigger box:
Length= 28 cm
Wrapping paper = x cm²
Box : wrapping paper = 24 cm : 936 cm²
Box : wrapping paper = 28 cm : x cm²
Equate both ratios to find x
24 : 936 = 28 : x
24/936 = 28/x
Cross product
24 * x = 936 * 28
24x = 26,208
x = 26,208 / 24
x = 1,092 cm²
Bigger box:
Length= 28 cm
Wrapping paper = 1,092 cm²
The answer to the question
Answer: The coordinates of the circumcenter is
.
Explanation:
The coordinates of triangle DEF are D(1,3) E (8,3) and F(1,-5).
Distance formula,




Since triangle follows pythagoras theorem,

Therefore the given triangle is a right angle triangle.
Or plot these points on a coordinate plane. From the figure we can say that the triangle DEF is a right angle triangle.
The circumcenter of a right angle triangle is the midpoint of the hypotenuse.
The hypotenuse is EF. The midpoint of EF is,

Therefore, the coordinates of the circumcenter is
.
X^2+y^2-6x+2y-36=0. Use the equation of the circle (x-h)^2+(y-k)^2=radius^2, center (h,k) is (3,-2)
