Answer:
2884.8 millimeters squared
Step-by-step explanation:
Given:
The radius of the disc is 35 millimeters, so the area of it is:
π
= 3.14*
= 3846.5
Then, we find out the area of the circular hold cut out of the bigger one, its radius is a haft of the radius of the bigger circle = 35/2 = 17.5
π
= 3.14*
=961.6
=> the area of the pendant = 3846.5 - 961.6 =2884.8 millimeters squared
Their would be 21 different solutions for this problem
Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
Base perimeter = 4 * 18 = 72 inches
Base Area = 18*18 = 324 square inches
Pyramid Surface Area = (.5 * 72 * 12) + 324
Pyramid Surface Area = 432 + 324
Pyramid Surface Area = 756 square inches

just fyi, if you spend x points on question, each user gets x/2 points (rounded up or down, I don't remember)
simple interest formula is
I=PRT
I=interest
P=principal
R=rate in decimal
T=time in years
assuming you mean that the principal is $2500 and not 2500 cents or 2500 of some other currency
interest=500
R=4%=0.04
I=PRT
500=(2500)(0.04)(T)
500=100T
divide both sides by 100
5=T
answer is 5 years
