Answer:
19.6 cm²
Step-by-step explanation:
The formula of the area of a circle
= πr²
The radius of the circle
= 5÷2
= 2.5 cm
The area of the circle
= π×2.5²
= 19.63495...
= 19.6 cm² (rounded to the nearest tenth)
Answer:
Both rates and ratios are a comparison of two numbers. A rate is a specific type of ratio. The difference is that a rate is a comparison of two numbers <u>with </u>different units, where for a ratio compares two numbers with the same unit.
In order to know the equivalent expression of the given above, all we need to do is to simplify it. So, for the exponents, what we need to do is just subtract.
The final answer would be 3/2xy^3. So the answer is option C. Hope this is the answer that you are looking for.
