Answer:
Formula for area of a circle;
<u>A = πr^2</u>
where pi is 3.14 in this case, and r is the radius squared
Plug in the actual values;
A = 3.14 x 11^2
A = 3.14 x 121
A = 379.94 square feet
Answer:
Actual length of w is 0.075 units.
Step-by-step explanation:
Given the actual length of side t is 0.045 cm.
we have to use the scale drawing to find the actual side length of w.
As given the actual length of t is 0.045 cm.
Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.
Scale factor is 
Hence, we get the scale factor.
Now, 
⇒ 
⇒ Actual length of w is 
Option B is correct.
