The formula to find the area of a circle is: π r squared. So, 4.5 π squared = about 63.62

Area = π . r² = 3.14 × 4.5² = 63.62 square units.
In terms of circumference:

Area = C2/(4π) = 28.272/4π = 799.19/(4 × 3.14) = 799.19/(12.56) = 63.62 square units.

I hope this helped.... ;)

Answer:

The answer to your question is x = 21

Step-by-step explanation:

Equation

$\frac{2}{7} x = 6$

- Multiply both sides by 7

$\frac{(2)(7)x}{7} = 6(7)$

- Simplify

2x = 42

- Divide both sides by 2

$\frac{2x}{2} = \frac{42}{2}$

- Simplify

x = 21

The value of 33 + 42 = ___.

frez [133]

Answer:

Step-by-step explanation:

We line up the tens place of 33 and 42 as well as the ones place so that it looks like:

+42

--------

Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.
