Answer:
38.485(correct to 5 significant figure)/ 12.25π
Step-by-step explanation:
=38.485(cor. to 5 sig.fig.)/ 12.25π
to find arc length of sector,we need to π(radius²)(sector's degree divided by 360 degree)
Answer:
0.6625
Step-by-step explanation:
To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,
Area of square is A=s*s=0.25*0.25=0.0625.
Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.
There are four equal triangles so together there area is 4*0.15 = 0.60.
Add the square to it and you have the surface area of the pyramid.
0.0625 + 0.60 = 0.6625
Answer:
I would say that C is the correct answer
Answer:
I think Yukari Yakumo or Sakuya
Step-by-step explanation:
Answer:
2. a1 = 10 and an = a(n-1) + 2
Step-by-step explanation:
10 is our first term so it would be a of 1.
Then, in this arithmetic sequence, it is increasing by 2.
So, therefore our recursive formula for this arithmetic sequence would be:
a(n) = a(n-1) + 2
