Answer:
I think I explained the circle one before so I'll explain the left question because I wanted some points.
here,
area of circle is πr² which is given= 12 π cm²
so πr²= 12π
r= 2√3
d= 2r= 4√3
AB is diameter so AB= 4√3
Answer: 66
Step-by-step explanation: Basically you want to find the area of the whole shape and the white shape, which the whole shape is 96 and the white shape is 30, and subtract 96-30=66
It would take Alexandria 8 months to earn the money.
125-20= 105 monthly earnings after personal expenses
800/105= 7.6 which rounds to 8.
8x105= 840
14.4 rounds to about 14 as a percentage that is 14%
