To answer the given question, substitute the values given to the equation,
S = π x sqrt(r² + h²)
155 m = π x sqrt (r² + (21 m)²))
r = 44.65 m
Therefore, the radius of the cone is approximately 44.65 m.
Answer: $54.50
Step-by-step explanation: If the bank account is currently overdrawn by $25.50, and then they deposit $20 per month for four months, they will have $54.50 in the account at the end of 4 months.
It is solved by multiplying 4 months x $20 = $80
Next, subtract (or add a negative) -$25.50 = $54.50
The answer to your question would be -10
22.9 is the closest but not exact. It was probably rounded off.
I used the formula: leg^2+leg^2=hypotenuse^2
(You can use that formula for any right triangle.)
