Answer:
Step-by-step explanation:
The television takes the shape of a rectangle whose width is 25 inches and whose height is 18 inches. To determine the length of the diagonal, we will apply Pythagoras theorem. It states that
Hypotenuse^2 = opposite^2 + adjacent^2
From the given information,
Adjacent side = 25 inches
Opposite side = 18 inches
Diagonal = hypotenuse.
Therefore
Diagonal^2 = 25^2 + 18^2
Diagonal^2 = 625 + 324 = 949
Take square roots of both sides of the equation, it becomes
Diagonal = √949 = 30.805 inches
Approximately 30.8 inches to the nearest tenth.
Answer:
-2(4-1)
Step-by-step explanation:
Do parentheses first because of PEMDAS. That means 4-1 equals 3. Then take -2 and times it by the 3 to get -6.
Answer:
28.26 in
Step-by-step explanation:
Radius = (1/2) diameter
Radius = (1/2)(9)
Radius = 4.5 in
Circumference = 2πr
Circumference = 2(3.14)(4.5)
Circumference = 28.26 in
