What is the surface area of a cone with a lateral surface area of 25 square inches and a base diameter of 4 inches? (Use 3.14 as an approximation for π.)

Step-by-step explanation:

SA = πr2 + πrl

l2 = h2 + r2

l2 = 52 + 32

l2 = 25 + 9

l = √(34)

l = 5.83 cm

And the total surface area of the cone is:

SA = πr2 + πrl

SA = π · r · (r + l)

SA = π · 3 · (3 + 5.83)

SA = 83.17 cm2

Therefore, the total surface area of the cone is 83.17cm2

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
