Question

what is the volume and surface area of a frustum of a right circular cone​

Answer 1

Answer:

Vol(Frustum)= 1/3*h*pi*(R^2+r^2+Rr)

TSA(frustum)= pi*l*(r+R)+pi(R^2)+pi(r^2)

PLS MARK AS BRAINLIEST!!!

Answer 2

Answer:volume of frustum = 1/3 pie h(R²+r²+Rr)

Total surface area=pie*R²+pie*r²+pie (R+r)l

Lateral surface area=pie(R+r)l
