<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>Let's find 'c' using Pythagoras theorem.</u>
- => c² = 8.4² + 4.3²
- => c² = 70.56 + 18.49
- => c² = 89.05
- => c = √89.05
- => c = 9.437 = 9.4 (Estimated)

Answer:
V = 150 pi units ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = pi 10^2 * 15
V = 1500 pi units ^3
Answer:
19
Step-by-step explanation:
-9b -5 -7b = -309
-16b - 5 = -309
16b = 309 - 5
16b = 304
b = 304 ÷ 16
b = 19
Answer:
C = -4
Step-by-step explanation:
First, combine like terms (terms with the same amount of variables):
14 = -2C - 3C - 6
14 = (-2C - 3C) - 6
14 = (-5C) - 6
Isolate the variable, C. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and equals:
Parenthesis
Exponents & Roots
Multiplication
Division
Addition
Subtraction.
First, add 6 to both sides:
14 (+6) = -5C - 6 (+6)
14 + 6 = -5C
-5C = 20
Next, divide -5 from both sides:
(-5C)/-5 = (20)/-5
C = 20/-5
C = -4
-4 is your value for C.
