The cone shown below has a slant height of 15 centimeters and a height of 12 centimeters. What is the radius of the cone.

Rzqust [24]

Answer:

The answer to your question is 9 cm

Step-by-step explanation:

Data

slant height = 15 cm

height = 12 cm

radius = ?

Process

To solve this problem, use the Pythagorean theorem. The slant height is the hypotenuse, the height is the long leg and the radius is the short leg.

c² = a² + b²

slant height² = height² + radius²

-Solve for radius

radius² = slant height² - height²

-Substitution

radius² = 15² - 12²

-Simplification

radius² = 225 - 144

radius² = 81

-Result

radius = 9 cm

At the fair Craig has 232 ride tickets each ride on the Ferris wheel costs 6 tickets after riding the Ferris wheel as many times

faltersainse [42]

Answer:

Criag have left with 4 tickets .

Step-by-step explanation:

Criag have total no. of ride tickets = 232

Each ride of the Feris Wheel cost no. of tickets = 6

6 tickets are required to cover each ride of Feris wheel

So, 232 tickets are required to cover no. of rides of Feris wheel = $\frac{232}{6}$

232 tickets are required to cover no. of rides of Feris wheel = $\frac{232}{6}=38.66$

1 ride of Ferris wheel cost no.of tickets = 6

38 rides of Ferris wheel cost no.of tickets = $6 \times 38 =228$

So, Tickets left = 232-228=4

Hence Criag have left with 4 tickets .
