Answer:
43
Step-by-step explanation:
we have two rectangles so we will divide them into 2.
first rectangles is 7m and 4m. 7 x 4 = 28
2nd rectangles is 3m and 5m 3 x 5 = 15
15 + 28 = 43.

Answer:
10 cm
Step-by-step explanation:
The volume of the cylinder is 1884 cubic centimetres and its height is 6 cm.
The volume of a cylinder is given as:
where r = radius
h = height
To find the radius of the base of the cylinder, we make r the subject of the formula and solve it:
Divide both sides by πh:
Find the square root of both sides:
Let us find the value of r:
=> r = 9.9975 cm ≅ 10 cm

Answer: 64 cm^2</h3>
Reason:
The parallelogram has area of A = base*height = 10*7 = 70 cm^2
The white rectangle has area of B = base*height = 3*2 = 6 cm^2
The shaded region has area of A - B = 70 - 6 = 64 cm^2
If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
3 hours
You can turn this into an equation:
F = 26 + 31t
Where F is the money Ralph earned, and t is the number of hours he worked.
Plugging in the 119 for F, we get
119 = 26 + 31t
93 = 31t
3 = t
