Answer:
A = 9 pi cm^2
Step-by-step explanation:
Circumference = 2 * pi *r
6pi = 2 * pi *r
Divide each side by pi
6 = 2r
Divide by 2
6/2 = 2r/2
3=r
Now we want to find the area
A = pi r^2
A = pi (3)^2
A = 9 pi cm^2
Question 1 is either B or D
Answer:
x = -7
Step-by-step explanation:
<u>Step 1: Distribute</u>
1/3(24x - 54) = 11(x - 4) + 5
8x - 18 = 11x - 44 + 5
<u>Step 2: Solve for x</u>
8x - 18 = 11x - 44 + 5
8x - 18 - 11x + 18 = 11x - 39 - 11x + 18
-3x / 3 = -21 / 3
x = -7
Answer: x = -7
STEP-BY-STEP SOLUTION:
Let's first establish the inequality which we need to solve as displayed below:
y + 1 < 3
To begin with, we need to make ( y ) the subject by keeping it on the left-hand side of the inequality and placing all other numbers on the right-hand side of the equality as displayed below:
y + 1 < 3
y < 3 - 1
Then, we simply simplify / solve as displayed below:
y < 3 - 1
y < 2
ANSWER:
y < 2
