Answer:
18.21 cm^2.
Step-by-step explanation:
Area of the unshaded part
= area of the square - area of the quadrant
= 7^2 - 1/4 pi *7^2
= 49 - 30.788
= 18.21 cm^2.
Answer: I think the answer is 3
Step-by-step explanation: I Divided 12 by 4 and got the answer 3
W= width
l= 2w= length
Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation
180= 2(2w + w)
multiply 2 by parentheses
180= 4w + 2w
combine like terms
180= 6w
divide both sides by 6
30 yards= w
LENGTH
2w= 2(30)= 60 yards
CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180
ANSWER: the width is 30 yards and the length is 60 yards
Hope this helps! :)
Answer:
34
Step-by-step explanation:
3n + 7 = 5n -11 (because of SAS)
-2n = -18
n = 9
yZ = 3(9)+7 = 34
