The diagram shows a sector of a circle with centre o. the radius of the circle is 8 cm. the point p on oa is such that 2op=3qr and the point q on ob is such that 4oq=3qb. given that angle aob =0.8 radians. calculate giving your answer correct to 2 decimal places. a)the length of the arc ab. b)the length of the line pq. c)the area of the shaded region

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

they aren't great and cause destruction, idk man

on the middle line

step-by-step explanation:

1/5=50
