Answer:
23.9425 (Round if needed)
Step-by-step explanation:
This is 2 half circles so you can find the area of a circle and divide it by 2.
First circle has a diameter of 6 cm
6/2=3 cm
So, circle has radius of 3.
Area of circle= 3.14(pi) radius^2
3.14 x 3^2= 28.26
28.26/2=14.13 cm
Area of first half circle= 14.13
Repeat that process for the second circle.
3.14 x 2.5^2=19.625
19.625/2=9.8125
14.13+9.8215=23.9425
Area=23.9425
Answer:
9 cm
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ← s is the side of the cube
Given V = 729, then equating gives
s³ = 729 ( take the cube root of both sides )
s = = 9

Answer:
h = 7.5 foot
Step-by-step explanation:
Given that,
John has a 10 foot ladder leaning against a wall at an angle of elevation of 53.13 degrees.
We need to find the height where the ladder meet with the wall.
Let Perpendicular = 10 foot
Angle of elevation,
Let h be the height (Hypotenuse). Using trigonometry,
So, the ladder will meet the wall at a height of 7.5 foot.
Answer:
Y' (3, 3 ) , Z' (2, - 1 )
Step-by-step explanation:
Given
X (3, - 1 ) → X' (6, 1 )
This represents + 3 in the x- direction and + 2 in the y- direction
Then the translation rule is
(x, y ) → (x + 3, y + 2 ) , then
Y (0, 1 ) → Y' (0 + 3, 1 + 2 ) → Y' (3, 3 )
Z (- 1, - 3 ) → Z' (- 1 + 3, - 3 + 2 ) → Z' (2, - 1 )
