Answer:
1469.52
Step-by-step explanation:
V=πr²h
r=6 ft
h=13 ft
π≈3.14
V≈3.14×6²×13 ft³
V≈1469.52 ft³
Answer:
and 
Step-by-step explanation:
(a)
A =
× 4
× 
= 2
× 
=
×
← rationalise the denominator
=
units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4
)² + (
)²
= 32 + 
=
+ 
=
( take the square root of both sides )
h =
=
×
← rationalise the denominator
h =
