Help (this for a friend)<br> a 62.1<br> b 117.4<br> c 122.1<br> d 164.5
kramer

Answer:

c. 122.1 cm

Step-by-step explanation:

so l * w + \frac{\pi r^2}{2}

since 6 cm is the diameter

6/2 = 3

the radius (or r) is 3

so 18 * 6 + \frac{3.14 * 3*3}{y}

108 + \frac{3.14*9}{y}

108 + \frac{28.26}{2}

108 + 14.13 = 122.13

simplified: 122.1 cm

hope this helps:)

A rectangle Has an area of 252 yd.². The length of the rectangle is 10 yards longer than twice it’s worth. Find the width and le
Rama09 [41]

Answer:

Width = 9 yds

Length = 28 yds

Step-by-step explanation:

Width = x

Length = 2x + 10

Area is 252 yd²

x(2x + 10)  = 252

2x² + 10x - 252 = 0

2 (x + 14) (x - 9) = 0

(x + 14) (x - 9) = 0

x = - 14 or x = 9

Width = 9 yds

Length = 2x9 + 10 = 28 yds
