Answer:
Step-by-step explanation:
Present value formula;
(PV) =
FV= Future amount (A) = $30,000
r = interest rate; monthly rate in this case = 7% / 12 = 0.5833% or 0.005833 as a decimal
n= total duration of investment (in months) in this case= 7*12 = 84 months
Next, plug in the numbers into the formula;
PV =
=18,405.48747
Therefore present value rounded to 2 decimal places = $18,405.49

Total surface area of the cone is 224π cm²
Step-by-step explanation:
- Step 1: Find total surface area when radius = 7 cm and height = 24 cm. Find slant height, l using Pythagoras theorem.
l² = h² + r² = 24² + 7² = 576 + 49 = 625
∴ l = √625 = 25 cm
Total surface area of the cone = πrl + πr² = πr(l + r)
= π × 7 (25 + 7)
= π × 7 × 32 = 224π cm²
