Surface area = 17*(sqrt(1155) + 19)
h^2 = 19^2 - 17^2/4
=> h = sqrt(4*19^2 - 17^2)/2 = sqrt(1155)/2
Surface area = 4(1/2*h*17) + 17*19 = 17(sqrt(1155) + 19)
Answer:
$3.90 is the answer.
Step-by-step explanation:
9.75 ÷ 2.5 = 39/10 (3.9).
To check do 3.9 × 2.5 = 9.75.
24km^2 is your answer because it’s squared
Answer:
Step-by-step explanation:
(x,y)→(x+5,y)
(-4,-1)→(-4+5,-1)=(1,-1)
reflection about x-axis
(x,y)→(x,-y)
(1,-1)→(1,1)
