Answer:
see below
Step-by-step explanation:
given:
radius of a circle = 3cm
find:
1. diameter
2. radius
3. r²
1) diameter = twice the radius = 2 r = 2 (3) = 6 cm
2) radius = 3 cm
3) r² = 3² = 9 cm
it can be 8 on each side or 7 9 and 8 or any 3 numbers you can add together to get 24.
Replace x with 3:
y = -3 *4^3
y = -3 * 64
y = -192
C is the correct answer.
The reason it is C is because pi/the symbol on top is irrational.
