A road construction marker is in the shape of a cone that has a slant height of 2.5 meters. If the curved surface area of the cone is 6.28 square meters, find the diameter of the cone.

the diameter of the cone is 1.6m

Step-by-step explanation:

The formula for determining the curved surface area of a cone is expressed as

Area = πrl

Where

r represents the radius of the cone.

l represents the slant height of the cone.

π is a constant whose value is 3.14

From the information given,

the curved surface area of the cone is 6.28 square meters

slant height = 2.5 meters.

Therefore,

3.14 × 2.5 × r = 6.28

7.85r = 6.28

r = 6.28/7.85

r = 0.8

Diameter = 2 × radius

Diameter = 2 × 0.8 = 1.6 meters

its d. the first coordintaes are 10,32
