Answer:
1: 64π
2: 49π and 153.86
Step-by-step explanation:
For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)
To find the area of a circle use the following formula
π*r² where r is the radius
This means that the first answer is π*8^2
which is 64π
For the second one it's the same deal but the radius is 7
so the answer is 49π
The measure of the amount of space in the object is the volume.
Answer:
As can be observed, every term in the given sequence: 2, 4, 6, 8, ..., is an even positive integer, and is, therefore, a multiple of 2:
1st term: 2 = 2(1)
2nd term: 4 = 2(2)
3rd term: 6 = 2(3)
4th term: 8 = 2(4)
Additional terms:
5th term: 10 = 2(5)
6th term: 12 = 2(6)
7th term: 14 = 2(7)
8th term: 16 = 2(8)
Therefore, using this same pattern, we see that the nth term of the given sequence is: 2n, where n is a positive integer that indicates the desired term of the sequence. For example, the 500th term of the sequence is: 2n = 2(500) = 1,000.
The ordered pair (-1, 6) is the solution to the system of equations.
Step-by-step explanation:
Given equations are;
3x+2y=9 Eqn 1
y=4x+10 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
Dividing both sides by 11
Putting x=-1 in Eqn 2
Solution: (-1, 6)
The ordered pair (-1, 6) is the solution to the system of equations.
