Notes:
In line 2, I replaced r with 2t because the radius r is increasing at a rate of 2 cm per second. So if t is the number of seconds, then 2t is the radius in cm at time t.In line 4, I multiplied both sides by 3 to clear out the fractions. On the next line, I divided both sides by 4pi.Related Questions

The value of tan 60° in the triangle ABC is √3
Right angle triangle:Right angle triangle have one of its angles as 90 degrees. The sides are called hypotenuse, adjacent and opposite side base on the angles.
Therefore,
ΔABC
∠C = 90°
AB = 12
BC = 6
∠B = 60°
∠A = 30°
Therefore,
tan 60° = opposite / adjacent
AC = √12² - 6² = √108 = 6√3
tan 60° = AC / BC
tan 60° = 6√3 / 6
tan 60° = √3

Mae Ling earns a weekly salary of $335 plus a 7.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,700 worth of merchandise?
Answers
Answer:
She made $664 during that work week.
Step-by-step explanation:
As Mae Ling earns $ 335 per week plus a commission of 7% with respect to the value of the sales she makes, and in the week she made sales for $ 4,700, to determine how much money she earned in the week the following calculation must be made:
335 + (4,700 x 7/100) = X
335 + (32,900 / 100) = X
335 + 329 = X
664 = X
Therefore, during that week Mae Ling earned $ 664.

Richard bought 3 pounds of bananas for $1.50. A banana weighs about 8 ounces and there are 16 ounces in a pound. At this rate, how many bananas can Richard buy for $5?
Answers
Answer:
Richard can buy 20 bananas for $5
Step-by-step explanation:
∵ Richard bought 3 pounds of bananas for $1.50
∵ 1 pound = 16 ounces
∴ 3 pounds = 3 × 16 = 48 ounces
→ That means Richard bought 48 ounces for $1.50
∴ The cost 48 ounces = $1.50
∵ A banana weighs about 8 ounces
→ Let us find 48 ounces equal to how many bananas
∵ 48 ÷ 8 = 6
∴ The 48 ounces are the weighs of 6 bananas
∴ The cost of 6 bananas = $1.50
→ To find how many bananas can he buy by $5, use the ratio method
→ Cost : Banana
→ 1.50 : 6
→ 5 : x
→ By using cross multiplication
∵ 1.50 × x = 5 × 6
∴ 1.50x = 30
→ Divide both sides by 1.50
∴ x = 20
∵ x is the number of bananas
∴ Richard can buy 20 bananas for $5
