Answer:
706.5 cm^2
Step-by-step explanation:
First we need to find the r to find the area of the base which is the circle so we use the volume to find r
V = 1/3πr^2h now adjust the equation for r
r = √3V/πh
r = √3(4710)/20π
r= 15
now that we have r, the base of cone is a circle so we use the area formula for circle
area = πr²
area = 3.14 (15)^2
area of base = 706.5 cm^2

Step-by-step explanation:
Answer:
21
Step-by-step explanation:
Volume= (4/3)*pi*r^3
40007= (4/3)*pi*r^3
r=21m
