Area rectangle: L * W
5 * 9
Area triangle: (1/2) * b * h
(1/2) * 3 * 4
Rectangle = 45
Triangle = 6
45 + 6 = 51 cm^2
Your answer is 8500 because 850 times 10 equals 8500
Answer:
12.56 in squared
Step-by-step explanation:
the formula for area is radius x radius x pi
So you do 2x2x3.14
(I would just do 4x3.14)
And then you get 12.56
Answer:
3 sqrt(10)
Step-by-step explanation:
To find the distance, we use the formula
d = sqrt( ( x2-x1)^2 + (y2-y1)^2)
= sqrt( ( 2- -1)^2 + ( -4-5)^2)
= sqrt( (2+1)^2 +(-4-5)^2)
= sqrt( 3^2 +(-9)^2)
= sqrt( 9+81)
= sqrt(90)
= sqrt ( 9*10)
3 sqrt(10)
6). y=3
7). x=-2
I hope this helped.
