Question

The lateral area of a right cone which has a base diameter of 4 units and a height of 10 units is:

Answer 1

Answer:

≈64.08

Step-by-step explanation:

Lateral Area=πr$\sqrt{h^{2} +r^{2} }$

Radius is 1/2 of the diameter so r=2

Height=10

Substitute:

: $3.141(2)\sqrt{10^{2}+2^{2} } \\6.282\sqrt{100+4} \\6.282\sqrt{104} \\ 64.066.282*10.2\\ 64.076$

64.076 rounded = 64.08
