Answer:
Step-by-step explanation:
1: Base Surface Area = π×72
= 153.9380400259 millimeters2
Lateral Surface Area = π×7×√72 + 142
= 344.215921821 millimeters2
Total Surface Area = 498.1539618469 millimeters2
Rounded = 500 millimeters2
2:Base Surface Area = π×52
= 78.539816339745 centimeters2
Lateral Surface Area = π×5×√52 + 102
= 175.62036827602 centimeters2
Total Surface Area = 254.16018461576 centimeters2
Rounded 300 centimeters2
X - the number of sandwiches

I don’t know #1 but here are the other ones:
2. 6
3. 4
4. 16
Answer:
c. 3.162
Step-by-step explanation:
the square root of 10 is 3.162
P(5 or 8) =
=
or 16.666%.
Step-by-step explanation:
Step 1; To determine the chances of a particular event to occur, we divide the number of outcomes that are favorable by the number of possible outcomes. In this case, the favorable outcomes are those which have both 5 and 8 in their 2 digit number and the number of outcomes is a count of all the ways in which the four numbers 6, 5, 1 and 8 can be used to form any two-digit numbers.
Step 2; From the tree diagram, we infer that there are two numbers that can be formed with both 5 and 8 i.e. 58 and 85. The total number of possible outcomes is 12 i.e. 65, 61, 68, 56, 56, 58, 16, 15, 18, 86, 85 and 81.
So P(5 or 8) =
=
=
= 0.1666 × 100 = 16.66%.
