A) 3000 * 0.5 = 1500 minutes, or 25 hours.
b) 10,000 * 0.5 = 5000 minutes, or 83 hours and 20 minutes
c) she works 2 hours a weekday. 2 hours = 120 minutes. It takes her 83 hours and 20 minutes to finish a 10,000 piece puzzle. It will take her 42 weekdays to finish this. Jan 15, 2020 is a Wednesday. She will finish it on March 12, 2020.

Answer:
The area of the cone is "1,695.6 cm³".
Step-by-step explanation:
The given values are:
Diameter of cone,
d = 18 cm
then,
Radius,
r =
=
=
Height,
h = 20 cm
As we know,
⇒ Area of a cone =
On substituting the given values in the above formula, we get
⇒ =
⇒ =
⇒ =
⇒ =
1. N is a midpoint of the segment KL, then N has coordinates
2. To find the area of △KNM, the length of the base MK is 2b, and the length of the height is a. So an expression for the area of △KNM is
3. To find the area of △MNL, the length of the base ML is 2a and the length of the height is b. So an expression for the area of △MNL is
4. Comparing the expressions for the areas you have that the area is equal to the area . This means that the segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas.
To find the volume, you multiply length times width times the height
