Answers
Answer 1
Answer:
We are tasked to solve for the lateral area of a right circular cone given that the base diameter measurement is 4 meters and the slant height measurement is 15 meters. To solve this problem, we need to use the formula below:
Lateral Area = pi*r (√h²+r²)
where r is half of the diameter measurement such as:
radius = r = diameter / 2
r = 4/2
r = 2 meters
Solving for the lateral area, we have it:
Lateral Area = 3.14*2 (√15²+2²)
Lateral Area = 94 m²
The answer is the letter "C".

Every positive number has two square roots.
The square roots of 67 are 8.185... (rounded) and -8.185... (rounded) .
Both are irrational numbers, so they can't be completely written down
with digits. No matter how many decimal places I write, it can never be
enough, because these decimals go on forever and never end.

Answer:
sales-tax rate = 6%
Step-by-step explanation:
The price of a silk scarf is $32. The sales tax is $1.92
Let the sale tax rate be s%
Price of silk scarf = $32
Sale tax = s% of 32
Sale tax = $1.92
Thus,
s% of 32 = 1.92
First we change s% to decimal
Hence, The sales-tax rate is 6%
The sales tax =1.92/32.00=0.06=6%
