Are these geometric and if they are whats the common ratio 1. 3, -30, 300,-3000 2. 5, 10, 15, 20 3. 4, 2, 1, 1/2

(x, y)→(x − 8, y − 7)

step-by-step explanation:

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 !

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
