Answer:
Part 1= Pi * R Squared
Part 2: 50.27
Part 3: 78.54
Part 4: 28.27
Step-by-step explanation:
Part 1: Memorize the formula
Part 2: 8 feet diameter = Pi * 4 squared. 8 feet is the diameter so the radius is 4. 4 squared is 16. 16 * pi = approximately 50.27, but is 50.24 if 3.14 is used as pi.
Part 3: Pi * 5 squared since 10 is diameter. 25 * pi which is close to 78.54, but is 78.5 is 3.14 is used for pi.
Part 4: I subtracted Part 3 from Part 2.
Answer:
Total number of ways 6 red marbles can be chosen=541549008
Step-by-step explanation:
16 marbles are chosen in which 6 are red marbles and remaining marbles ,which are 10, are blue marbles.
In order to find in how many ways 6 red marbles can be chosen we will proceed as:
Out of 17 red marbles 6 are chosen and out of 18 blue marbles 10 are chosen.
Total number of ways 6 red marbles can be chosen=
Total number of ways 6 red marbles can be chosen=
Total number of ways 6 red marbles can be chosen= 12376*43758
Total number of ways 6 red marbles can be chosen=541549008
Answer: -20
Step-by-step explanation:
We can set up an equations with the conditions we are given. Let's use x for the missing number.
2(x-4)=3(x+4)
2x-8=3x+12
-20=x
Answer:
Angle C > Angle A > Angle B
Step-by-step explanation:
Given the side lengths, we want to know how big the angles are
Mathematically, the bigger the angle, the bigger the side length that faces it
AB is the biggest side length and the angle that faces it is the angle C
BC faces the angle A
AC faces the angle B
so we have it that;
Angle C > Angle A > Angle B
