Answer:
7^2 + 5^2 = 49 + 25 = 74
hypotenuse = square root of 74
Answer is B
Step-by-step explanation:
153.8 = 3.14r^2
Divide each side by 3.14 to get r alone.
48.9 = r^2
Take the square root of each side to isolate r.
r = 6.999
r= 7
Answer:
10 in.
Step-by-step explanation:
The area of a rhombus is the product of the lengths of the diagonals divided by 2.
Let the diagonals be x and y.
area = xy/2
Here you have
area = 40 in.^2
x = 8 in.
We are looking for y, the other diagonal.
xy/2 = area
(8 in.)y/2 = 40 in.^2
(8 in.)y = 80 in.^2
y = 10 in.
Answer: The other diagonal has length 10 in.
