Answer:

A = 78.5 cm²

Step-by-step explanation:

the area (A) of the circle is calculated as

A = πr² ( r is the radius )

here diameter = 10 cm , then r = 10 cm ÷ 2 = 5 cm , so

A = π × 5² = 25π ≈ 78.5 cm² ( to the nearest tenth )

what's the slope? simplify your answer and write it as a proper fraction,improper fraction or integer

dybincka [34]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

In this graph, when you count rise and run, rise would be 1 and run would be 2. Because slope is also known as rate of change and rate of change is also known as rise over run, the slope will be 1 over 2.
