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,
$\pi {1.85}^{2} \\ = \frac{1369}{400} \pi \\ or \\ = 3.4225\pi$

The perimeter of a triangle is 133 inches. If one side of the triangle is five more than the shortest side, and the longest side

barxatty [35]

133=x + (x+5) + (x+14)

133 = 3x+19

3x=114

x= 114/3 =38

5+38 =43

38+14 =52

check: 38 +43 +52 = 133

3 sides are : 38, 43 & 52
