Answer:
D) -0.87
Step-by-step explanation:
I took this test don't quote me on the answer but this is what my peers put.
6r - 3t = 6 /*8
6r + 8t = - 16 /*3
48r - 24t = 48
48r + 24t = - 48
---------------------- +
96r = 0
r = 0
t = ( -16 + 6r)/8 = - 16/8 = - 2
Answer:
The area of a circle is defined as πr², where r = the radius
In this problem, A = π(12)² = 144π square units
Pi is approximately 3.14
A = 144(3.14) = 452.16 square units
