Answer:
483.56 square milimeters
Step-by-step explanation:
In the above question, we obtain the following information:
Slant height = 15mm
Radius = 7mm
π = 3.14
Since we are given the slant height ,
the formula for surface area of a cone = πrl + πr²
= πr (l + r)
= 3.14 × 7(15 + 7)
= 3.14 × 7( 22)
= 21.98(22)
= 483.56 square milimeters
Answer:
P = 827
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
A = 884.89
r = 7%
n = 1 year
Step 2: Substitute
884.89 = P(1 + 0.07)¹
Step 3: Solve for <em>P</em>
884.89 = P(1.07)
P = 827
4 divided by 1/3 equals 12
