the answer is 120.00 dollars
Answer:
His error is multiplying by 4 sides as he thought it was total surface not lateral surface area- the final answer is 12
Step-by-step explanation:
He should have multiplied it by 3, because the 3 sides- not including the base- is what lateral surface area is. He originally did total surface area not lateral surface area so each sides area is 4m squared then you just multiply it by 3 and its 12
Estimate to nearest hundreds is 600
Estimate to nearest tens is 610 or 520
By definition, the volume of a cone is given by:
V = (1/3) * (pi) * (r ^ 2) * (h)
Where,
r: cone radius
h: height of the cone
Substituting values:
V = (1/3) * (3.14) * ((8/2) ^ 2) * (9)
V = 150.72 cm ^ 3
Answer:
this paper cone cup can hold:
V = 150.72 cm ^ 3
