Answer:

188.5 cm^2

Step-by-step explanation:

a) Your volume is correct.

b) The curved surface area of the cone is called the lateral area.

Its formula is:

LA = (pi)rs,

where pi is 3.14159...

r = radius of the base

s = slant height of the cone

Here, r = 6 cm, and s = 10 cm

LA = (3.14159)(6 cm)(10 cm)

LA = 188.5 cm^2

A man sold his house for $125,000. After paying he broker his commission, the man received $116,875. What was the broker’s commi
PilotLPTM [1.2K]

116875 = (x / 100) * 125000

116875 = x * 125000 / 100

116875 = 1250x (The zeros get cancelled)

Therefore, x = 116875/1250 = 187/2 = 93.5%
