Answer:

$\large\boxed{L.A.=168\pi\ in^2}\\\boxed{S.A.=232\pi\ in^2}$

Step-by-step explanation:

The formula of a lateral area of a cone:

$L.A.=\pi rl$

r - radius

l - slant height

The formula of a surface area of a cone:

$S.A.=\pi r^2+\pi rl$

We have r= 8in and l = 21in. Substitute:

$L.A.=\pi(8)(21)=168\pi\ in^2$

$S.A.=\pi(8^2)+168\pi=232\pi\ in^2$

oksano4ka [1.4K]

Answer:

the price of the shirt without discount is 75,000 pesos

Step-by-step explanation:

The computation of the price of the shirt without discount as follows:

There is a discount of 20%

And the person pays 60,000 pesos after considering the discount

So, the price without discount is

= 60,000 pesos ÷ 0.80

= 75,000 pesos

hence, the price of the shirt without discount is 75,000 pesos
