What is the best approximation of the surface area of this right cone

Mathematics
1 answer:
Tatiana [17]3 years ago
4 0
Use the formula for the surface area of a right cone:

\sf A=\pi rs+\pi r^2

Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):

\sf A=(3.14)(12)(15)+(3.14)(12)^2

Multiply and simplify exponent:

\sf A=565.2+(3.14)(144)

Multiply:

\sf A=565.2+452.16

Add, round to the nearest whole number:

\boxed{\sf A\approx 1017~cm^2}

Vlad1618 [11]

Answer:

Conrad had 56 sales on Monday , 168 sales on Tuesday and 504 sales on Wednesday.

Step-by-step explanation:

Let x be the no. of sales on Monday

We are given that On Tuesday Conrad had 3 times as many sales as on Monday.

So, Conrad had sales on Tuesday = 3x

We are also given that On Wednesday, he had 9 times as many sales as on Monday.

So, Conrad had sales on Wednesday = 9x

Over the three days, he had a total of 728 sales

So, x+3x+9x=728

13x=728

x=\frac{728}{13}

x=56

Conrad had sales on Tuesday = 3x =3(56)=168

Conrad had sales on Wednesday = 9x=9(56)=504

Hence Conrad had 56 sales on Monday , 168 sales on Tuesday and 504 sales on Wednesday.
