Question

IS anyone good in surface areas cones??? I need expert for brainlest and points​

Answer 1

Answer:

$A=90.6cm^2$

Step-by-step explanation:

Calculate the slant height using pythagorean theorem:

$6^2+4^2=l^2\\36+16=l^2\\l^2=52\\l=\sqrt{52} \\l=7.2111$

Use the slant height to calculate the lateral area:

$A=\pi rl$

$A=(3.14)(4cm)(7.2111cm)\\A=90.57.cm^2$
