Answer:
C
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( where r is the radius )
Here diameter = 8 cm , thus r = 8 ÷ 2 = 4 cm , thus
A = π × 4² = 16π cm² → C
Answer:
x = 145.2
Step-by-step explanation:
Convert 15.3 ft to inches = 183.6
Exquation:
183.6 - x = 38.4
-x = 38.4 - 183.6
-x = -145.2
x = 145.2
X=-6 and x=1/3 are both correct values so A and D
Step-by-step explanation:
12a-9a>-12+6
3a>-6/:3
a>-2
