Answer:

135 pi centimeters squared

Step-by-step explanation:

Hello!

where la is lateral surface area

first \: the \: formula \: for \: the \: lateral \: surface \: are \: of \: cone \: is \\ la = \pi \times r \times l \\ where \: r = radius \\ l = slant \: height \\ therefore.first \: find \: the \: radius(r) =  \frac{d}{2}  \\ r =  \frac{18cm}{2}  = 9cm \\ so \: as \: we \: have \: the \: radius \: we \: can \: solve \: for \: the \: la \\ la = \pi \times r \times l \\ la = \pi \times (9cm) \times (15cm) \\ la = 135\pi \: cm {}^{2}

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 p
Ber [7]

Answer:

Price $0.75 per ounce of confetti

Step-by-step explanation:

Given the statement: Yuki bought a pound of confetti for $12.

⇒1 pound = \$ 12                 ......[1]

Also, it is given that there are 16 ounces in 1 pound.

⇒ 16 ounces = 1 pound                       .....[2]

To calculate the price, in dollars per ounce of confetti.

From [1] and [2] we have;

16 ounces = \$12

then;

1 ounces =  \frac{12}{16} = \frac{3}{4} = \$0.75

Therefore, the price, in dollars per ounce of confetti is, $0.75  per ounce.
