Answers
1) we calculate the area of the circle.
area of the circle=πr²
r=13 in.
area of the circle=π(13 in)²=169π in²
2) we calculate the volume of the cylinder:
area (circle)=169π in²
height=30 in
volume=169π in² x 30 in=5070π in³ ≈ 15927.87 in³
Answer: 5070π in³ or 15927.87 in³

Answer:
13 units
Step-by-step explanation:
Use the pythagorean theorem and find the hypotenuse.
a^2 + b^2 =c^2
Draw the triangle by connecting the dots so you can see the legs.
one leg is 8 units and one leg is 10 units
8^2 + 10^2 = c^2
64 +100= c^2
164 = c^2
Find the square root of 164 which is 12.8. Round to 13

Answer:
x=1+/-4i
Step-by-step explanation:
(x+1)/3-(2x-1)/x=-1
find the common denominator,
in this case, it's going to be 3x.
(x^2+x)/3x-(6x-3)/3x=-1
(x^2+x-6x+3)/3x=-1
x^2-5x+3=-3x
x^2-5x-(-3x)+3=0
x^2-5x+3x+3=0
x^2-2x+3=0
apply the quadratic formula in order to find the roots for x.
Since ax^2+bx+c=0, in this case,
a=1, b=-2, c=3
--------------------------
x=(-b+/-sqrt(b^2-4ac))/2a
x=(2+/-sqrt(4-12))/2
x=(2+/-8i)/2
x=1+/-4i

Answer:
the answer would be 28.
Step-by-step explanation:
you're multiplying the top and bottom by 7. 3 *7=21 for the bottom
4*7 = 28 for the top
Hope this helps

Answer:
The answer is A. 28
Step-by-step explanation:
When you divide 21 into 3 you get 7.
So you have to multiply 7 to get 21. Whatever you do to the bottom or top you have to do to the opposite so you have to multiply 7 by 4 and you get 28.
Hope this helps

= 19/30*(100%)
(100%= 100/100= 1, so it does not change the outcome)
= 63.33%
The final answer is 63.33%~
This is because 19 divided by 30 is equal to about 0.63
THEN MULTIPLIED BY 100 WOULD EQUAL 63%
