a) 6¹/²

b) 6¹/⁴

c) 6⁴/³

d) 6⁷/¹²

a)

Step-by-step explanation:

Here, the given expression is:

Now, as we know that :

Applying same in the given expression, we get:

Also,

Now,

Hence,

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

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
