Answer:
B. 95
Step-by-step explanation:
Plug in 8625 into the equation as c:
c = 75n + 1500
8625 = 75n + 1500
Solve for n:
7125 = 75n
95 = n
So, 95 people attended.
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
