Find the lateral area of a cone with a radius of 7ft. and a slant height of 13ft. Use 3.14 for pi and round to the nearest tenth?
Solution:
Lateral area of a cone = πrL
Where r is the radius
L is the slant height
Radius of a cone = 7 ft
Slant height of a cone = 13 ft
Substituting the values we get
Lateral area of a cone = 3.14 × 7 × 13
By further calculation
= 285.74 ft2
= 285.7 ft2 [rounding to the nearest tenth]
Therefore, the lateral surface area of a cone is 285.7 ft2.
Find the lateral area of a cone with a radius of 7ft. and a slant height of 13ft. Use 3.14 for pi and round to the nearest tenth?
Summary:
The lateral area of a cone with a radius of 7ft. and a slant height of 13ft is 285.7 ft2.
