(asap, ! ) raj, amit, parul, and lara were asked to find the volume of the following i don't remember the formula. it looks easy if i knew what formula to insert here lol.

we know that

Volume of a cone=(1/3)*[B]*h

where

B is he area of the base

h is the height

Find the volume of a cone in each case

case a) Raj

h=3 cm

diameter=5 cm

so

radius r=5/2=2.5 cm

Area of the base B=pi*r²

B=pi*2.5²

B=6.25*pi cm²

V=(1/3)*6.25*pi*3=6.25*pi cm³

case b) Amit

h=4 cm

r=3 cm

Area of the base B=pi*r²

B=pi*3²

B=9*pi cm²

V=(1/3)*9*pi*4=12*pi cm³

case c) Parul

h=7 cm

Area of the base B=4*pi cm²

V=(1/3)*4*pi*7=(9.33)*pi cm³

case d)Lara

h=6 cm

Area of the base B=3*pi cm²

V=(1/3)*3*pi*6=(6)*pi cm³

therefore

the answer is

Parul

Parul is the correct answer.

I just took the quiz on edge

h
