What is the area of the circle in terms of pi? 3.7 m is the diameter
Liono4ka [1.6K]
Area of a circle is :
\pi {r}^{2}
Where r is the radius.
To find r, you divide the diameter by 2
\frac{3.7}{2}  = 1.85
Then,
\pi {1.85}^{2}  \\  =  \frac{1369}{400} \pi \\ or \\  = 3.4225\pi

IRINA_888 [86]
Convert 45% to a decimal by dividing it by 100. It becomes 0.45.

Multiply 0.45 onto 140.

You get 63. That’s how many eggs he sold.

What is the value of angle v?
Flauer [41]

Answer:

x = 5

Step-by-step explanation:

a) The third interior angle of this triangle is 180 - 20 x.  

The three interior angles must sum up to 180 degrees.

Therefore,  60 + 7x + 5 + 180 - 20x = 180, or

                       65  + 180 - 13x = 180, or

                               65 -  13x     = 0

Finally, 13x = 65, and so x = 5
