Total surface area of the cone: (pi*64)+(pi*8*15) = 184*pi or about 578 square units
Slant height of the cone = sqrt(32 + 152) = 15.297 Base surface area = π(3)2 = 9π Curve surface area = π(3)(15.297) = 45.891π Total surface area = 9π + 45.891π = 54.891π
Lateral area is 188.5 m2

The curved surface area of the cone is 801.11 square units.
Slant height of the cone = sqrt(32 + 152) = 15.297 Base surface area = π(3)2 = 9π Curve surface area = π(3)(15.297) = 45.891π Total surface area = 9π + 45.891π = 54.891π
Curved surface area = pi*2*15 = 94 square meters (to nearest integer)
It's about 172.466 More precisely, 9 (1+sqrt(26)) pi
Entire surface area of the cone: (pi*2^2) plus (pi*2*15) = 107 square m rounded
To find the surface area of a right cone, you can use the formula: ( \text{Surface Area} = \pi r (r + l) ), where ( r ) is the radius and ( l ) is the slant height. Substituting the given values, ( r = 3 ) and ( l = 12 ), the calculation is: [ \text{Surface Area} = \pi \times 3 \times (3 + 12) = \pi \times 3 \times 15 = 45\pi \approx 141.37 , \text{square units}. ] Thus, the surface area of the cone is ( 45\pi ) square units.
The lateral area of a right circular cone with a base diameter of 4 m and a slant height of 15 m is: 94.25 m2
