The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13

Iteru [2.4K]

Answer:

283 cm^2

Step-by-step explanation:

Solution:-

We have a cone with a circular base of radius r = 5 cm

The height of the cone is h = 12 cm

The slant height of the cone is L = 13 cm

We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:

Base Area : Circle

$A_1 = \pi r^2\\\\A_1 = \pi 5^2\\\\A_1 = 25\pi$

Curved Surface: conical

$A_2 = \pi * r*L\\\\A_2 = \pi * 5*13\\\\A_2 = 65\pi$

The total surface area of the cone can be written as ( A ):

$A = A_1 + A_2\\\\A = (25 + 65 )*\pi \\\\A = 90*(3.14) \\\\A = 282.7433 cm^2$

Answer: The surface area of the cone to nearest whole number would be 283 cm^2

The function y = -15x + 2100 can be used to model the height, y, of a parachute jumper x seconds after she jumps from an airplan

olganol [36]

Answer:

2100 units

Step-by-step explanation:

We want to find the y-intercept of the function $y=-15x+2100$ which can be used to model the height, y, of a parachute jumper x seconds after she jumps from an airplane.

To find the y-intercept, you substitute $x=0$ into the equation.

$y=-15(0)+2100$

Multiply by zero to get:

$y=0+2100$

Add zero to obtain:

' $y=2100$

Therefore the y-intercept, which is the initial height is 2100
