Step-by-step explanation:
square-based pyramid:
volume V = (⅓)b²h
= (⅓)7²·16
≅ 261.3 ft³
:::::
Can't help with question 3. I haven't learned triangle-based pyramids.

cone:
volume V = ⅓πr²h
= ⅓π17²·20
= 6052.8 yd³
:::::
can't help with question 7. Never did this kind of pyramid.
The formula for an area of a circle is A= pi(r)^2
so if you plug in 5 to r (because it’s the radius) you should get A= 78.5
Answer:
The answer is 7 1/24
Step-by-step explanation:
27/8 + 11/3
I multipled 27/8 by 3/3 (needed the 8 to become 24)
I multiplied 11/3 by 8/8 (needed the 3 to become 24)
We get:
81/24 + 88/24
Then you add
169/24
Simplify
7 1/24
