Answer:
r=5
Step-by-step explanation:
centre is (1,3)
r=√((4-1)²+(7-3)²)=√(9+16)=√25=5
r=5
Answer:
68 square meters
Step-by-step explanation:
The hexagon is made up of two trapezoids. Use the formula to find the area of each trapezoid then add those two areas together.
Area of a trapezoid (add the two bases together, multiply by the height then divide by 2):
Top trapezoid:
Bottom trapezoid (identical to the top trapezoid):
Add the areas together:
34 + 34 = 68
1 kg = 1,000,000 mg
55,000 mg = 55,000/1,000,000 = 0.055 kg
0.055 kg < 2 kg
so 55,000 mg < 2 kg
Answer:
Option C.
The two sums are equal.
Step-by-step explanation:
In geometry, the sum of the exterior angles of any polygon will always give 360 degrees. This is regardless of the type of polygon, whether it is a triangle, quadrilateral, pentagon, or a decagon.
This means that the sum of the exterior angles of a square is equal to that of the pentagon.
As the number of sides that they have increases, the sizes of their internal angles get smaller, making the sum of their external angles remain at 360 degrees
