2) What is the value of DE if AB = 6, AD = 8, and BC = 3?
A) 3.5
B) 4
C) 4.5
D) 5

B

Step-by-step explanation:

Δ ABC and Δ ADE are similar thus the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

6DE = 24 ( divide both sides by 6 )

DE = 4 → B

d

step-by-step explanation:

d

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
