Answer:
C. 22 sq. ft
Step-by-step explanation:
* 4
11 ÷ 2 = 5.5
5.5 * 4 = 22
The area of the trapezoid is 22 square feet
The second one, The fourth one, and the last one.
If p, the amount of people, is 12 then each person Will get 4 slices and there will be no slices left
If p, the amount of people, is 15, then each person will get 3 slices but there will be 3 slices left over
If p, the amount of people, is 16, then each person will get 3 slices of pizza with no leftovers.
Answer:
a. You can earn about $245
b. You will earn about $35 less if the lid is missing
Step-by-step explanation:
a. To solve this we first need to calculate the surface area of the drum, which has a cylinder shape, therefore it's surface area is given by:
surface area = 2*(pi*r² + pi*r*h)
r = d/2 = 4/2 = 2 ft
surface area = 2*(pi*2² + pi*2*5)
surface area = 2*(4*pi + 10*pi) = 2*14*pi = 28*pi ft²
surface area = 87.96 ft²
Since each square foot pays $2.79, then the total value of the drum is:
value = surface area * 2.79 = 87.96*2.79 = $245.42
b. If the lid of the drum is missing, then the surface area is given by:
area drum with no lid = surface area - lid area
area drum with no lid = 87.96 - pi*(2)² = 87.96 - 12.566 = 75.394 ft²
value = area drum with no lid * 2.79
value = 75.394 * 2.79 = 210.35
loss value = 245.42 - 210.35 = $35.07
Answer: 125.6 ml
Step-by-step explanation: V = (3.14) (2^2) (10)
V = (3.14) (4)(10)
V= 125.6 cm^3
1 cubic centimeter = 1 milliliter
8 4/5= 8 8/10
8 8/10- 5 1/10= 3 7/10
The 4th option is correct.
Hope this helps!
