Find the lateral area of the cone. Use 3.14 fo pi and round result to the nearest whole unit.
radius: 15cm
Side unit: 28cm
Please help!!
A) 1,319 cm squared
B) 2,639 cm squared
C) 707 cm squared
D) 2,026 cm squared
is the answer B?
It's actually
1. a
2. b
3. d
4. a
Psuedonym is right!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If by side unit, you mean "slant height"
then the area of the cone = πrl, where l is the slant height, so
Area = π(15)(28) = appr 1319
