Answer:
V = 339.12
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 6
h = 9
Work:
V = πr²(h/3)
V = 3.14(6²)(9/3)
V = 3.14(36)(3)
V = 113.04(3)
V = 339.12
Answer:
840cm²
Step-by-step explanation:
The two small triangle areas:
b × h / 2 = 12 × 5 = 60 / 2 = 30cm²
So two triangles would be 60cm²
Now, for the top rectangle:
b × h = 26 × 12 = 312cm²
The middle rectangle:
b × h = 26 × 13 = 338cm²
And the bottom last triangle:
b × h = 26 × 5 = 130cm².
Now to add them all: 60 + 312 + 338 + 130 = 840cm²
I advice you to just check to make sure the calculations were right! Good luck with the rest of your finals :)
Answer: The area is a = 6.25
Step-by-step explanation: Using formula P = 4 a
Solving for a
