What is the surface area of the cone? Express your answer in terms of π.b
weeeeeb [17]

Given:

Radius of the cone = 5 ft

Slant height of the cone = 21 ft

To find:

The surface area of the cone

Solution:

Surface area of cone formula:

SA=\pi r^{2}+\pi r l

where r is the radius and l is the slant height.

SA=\pi \times 5^{2}+\pi \times 5 \times 21

SA=\pi \times 25+\pi \times 105

SA=25 \pi+ 105 \pi

SA=130 \pi

The surface area of the cone is 130π square feet.

-7( x + 3 ) = -4 ( x-6 )
REY [17]

                                  -7(x+3)= -4(x-6)

                                  -7x - 21 = -4x + 24                              

                                   -21 = 3x + 24

                                     -45 = 3x

                                        x = - 15
