Correct principal is $1200.

R = 6.736%

Step-by-step explanation:

Formula for simple interest is;

Interest = PRT/100

We are given;

Principal; P = $1200

Time; T = 6 years

Interest; I = $485

Rate; R =?

From, Interest = PRT/100, we have;

485 = 1200 × R × 6/100

Making R the subject gives;

R = 485 × 100/(6 × 1200)

R = 6.736%

$35.59 in pounds

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
