Step-by-step explanation:
Given the information of the conical hat
- diameter of 16 inches => Radius = 8 inches
- height of 9 inches
=> the slant height of the hat is (use Pythagorean Theorem)
=
<=> =
<=> s =
The area (without the base area) of tissue paper will she need to make one hat is:
SA = πrs in2
<=> SA = π*8* in2
<=> SA =8 π
=> the total tissue paper will she need for 21 hats is:
SA*21
= 8 π*21
= 6352,18 in 2
Answer:
Step-by-step explanation:
Heat always flows from a hotter object to a colder one. If heat flows from the sphere to the water,
A is wrong. If the temperature of the water is greater than 8 °C, heat will flow from the water to the sphere.
B is wrong. If the temperature of the water is lower than 8 °C, heat will flow from the sphere to the water..
D is wrong. If heat flows from the water to the sphere, the temperature of the water will decrease.
