Ravi had a rope. he used 45cm of the rope to tie a parcel. he then cut the remaining rope equally into 4 pieces. each piece was 65cm long. (a) find the length of the rope left after tying the parcel. (b) how long was the rope at first

65 x 4 = 260 cm was left after tying the parcel

260 + 45 = 305 cm was the total length

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
