Answer:
Area of shaded region = 351.68 cm²
Step-by-step explanation:
Area of a circle = πr²
where r = radius = 3.14
Area of bigger circle = 3.14 × 11²
= 3.14 × 11 × 11
= 379.94cm²
Area of smaller circle = 3.14 * 3²
= 3.14 × 3 × 3
= 28.26cm²
Area of shaded region = Area of bigger circle - Area of smaller circle
= (379.94 - 28.26) cm²
= 351.68 cm²
Answer:
Choice B
Step-by-step explanation:
Given radical expression:
To Find:
The Simpler form of this expression
Soln:
We could re-write the given expression, according to the law of exponents:
Now we need to bring terms out of the radical as:
Bring out 6x^4 from the absolute & put y^3 only in it:
Choice B is accurate.
Answer:
Divide the 1st equation by 2
a + 2c = 19
Divide the 2nd equation by 3
a + c = 13.5
Subtract the 1st equation and the 2nd equation
c = 5.5
Substituting back into the 2nd equation will give:
a + 5.5 = 13.5
a = 8
Step-by-step explanation:
If 5 is a factor of the number, then its ones place is either a 5 or a zero.
