Need help with math plz thank you

Step-by-step explanation:

law of sines  

Sin(A) / a  = Sin(B)/b

where A = 24

a=BC

B= 59

b =AB

then

Sin(24)/a =Sin(59)/19

0.4067366 / a = 0.8571673 / 19

0.4067366 / a = 0.045114

0.4067366 / 0.045114 = a

9.015 = a

BC = 9.0 mi

answer: it's a

step-by-step explanation:

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
