Answer:
Find the area of table top( circle)
A=πd²/4
A = 3.1415× (90cm)²/4
A= 3.1415× 8100cm²/4
A= 3.1415×2025
A=6361.5375cm²
The area of the table top is 6361.5375cm².
Answer:456 thatas the answer
Step-by-step explanation:
<span>3x-5=5x+11
subtract 3x to both sides
</span>3x-5 - 3x =5x+11 - 3x
<span>simplify
-5 = 2x +11
answer is </span><span>D. -5=2x+11</span>
Answer:
x= -4
Step-by-step explanation:
2x+4=6x+20
so 2x-6x=20-4
divide both sides by -4
-4x/-4 = 16/4
=-4
