Answer:
100
Step-by-step explanation:
4 spirals for 1 student. 4 x 25 to get the total number, and that equals 100
Angle (8x)⁰ and angle (2x+60)⁰ are congruent angles as corresponding angles.
So,
8x = 2x+60
8x - 2x =60
6x = 60
x=10
Answer C. 10

Answer:
240.6 m²
Step-by-step explanation:
Mr samuel built a circular fenced-in section for some of his animals the section has a circumference of 55. What is the approximate area in square meters of the section? Use 22/7 for pie
Step 1
We have to find the radius of the circular fence
The circumference of a circle = 2πr
Circumference = 55m
Hence:
55m = 2 × 22/7 × r
55 = 44/7
r = 55 ÷ 44/7
r = 55 × 7/55
r = 8.75m
Step 2
We find the approximate area in square meters of the section.
Area of a circle = πr²
Area of the circle = 22/7 × 8.75²
Area of the circle = 240.625 m²
Approximately = 240.6 m²
Therefore, the approximate area in square meters of the section is 240.6m²
