Use Socratic it gives u a step by step explanation
Answer:
1st sphere has r1 = 6
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 6^2 = 144pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 6^3 =288pi
2nd sphere has r1 = 15
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 15^2 = 900pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 15^3 =4500pi
=> S1/S2 = 144pi/900pi = 0.16
=> V1/V2 = 288pi/4500pi = 0.064
Hope this helps!

A) Simple interest note proceeds are equal to the face value: $18,235.
b) Simple discount note proceeds are the face value less the inerest due,
.. $18,235(1 -0.10*2) = $14,588.

Search at symbolab derivative calculator and watch the steps there!
Since I'm not a tutor nor a teacher, it is very hard for me to show step-by-step, but I suggest you should view the (derivative) calculator.

box 1
y/x = 5/20 =1/4
y/x = 7/35 = 1/5
this is not proportion y/x is not the same
box 2
y/x = 15/40 = 3/8
y/x = 21/56 = 3/8
y/x = 27/72 = 3/8
this is proportional
y is 3/8 times x
