I need help

Help with this please(perimeter of the circle)

[jolly cradle]

we have to find area of the figure ryt?

= area of circle + area of sector
= π(5)^2 + (θ/360°) × πr^2

radius of sector is missing

[novel dome]

do you have any other information?

MathIsAlwaysRight

[novel dome]

but you need to know the r

Sorry I was told to find the perimeter of the circle

[novel dome]

Of circle or sector?

[ivory verge]

The question says "Find the lateral area of the cone in the figure below."

[novel dome]

Oh so it's cone, wonderful

[ivory verge]

So how do I go with it?

[novel dome]

so those to lengths must be equal

the red length is 2pi r

[ivory verge]

So if I'm calculating correctly it's 10π?

[novel dome]

Yep

Perimeter of the blue sector is 2pi*r*150/360

so 2pi*r*150/360=10pi

when you divide both sides by 2pi what do you get?

you need to solve for r btw

[ivory verge]

Which sides?
