Answer:
volume of the square pyramid is:
V = s2h/3
where s=side length and h= height
for square pyramid A
h(a)= 8in and s(a)=12in
volume of square pyramid for A =
V(a)=s2(a) h(a)/3
V(a)=122 . 8/3 \implies⟹ 144 . 8/3 \implies⟹ 1152/3 \implies⟹ 384 in3
for square pyramid B
h(b)=24in and s(b)=36in
volume of square pyramid for B =
V(b)=s2(b) h(b)/3
V(b)=362 . 24/3 \implies⟹ 1296 . 24/3 \implies⟹ 31104/3 \implies⟹ 10368 in3
We want to know how many times the volume of pyramid B is bigger than pyramid A :
= V(b)/V(a)
=10368/384
= 27 times

Answer:
4m
Step-by-step explanation:
We are looking for the circumference
We need to find the radius
r = d/2 = 1.2/2 = .6
C = 2*pi*r
C = 2*pi*(.6)
C = 1.2*pi
We can approximate pi by 3.14
C =1.2*3.14
C =3.768 m
To the nearest meter
C = 4m
Answer:
Circumference: 12π
Area: 36π
Step-by-step explanation:
The equation for the circumference of a circle is:
C = πd
Where C is the circumference and d is the diameter. Knowing this, we will be able to find the circumference by pugging in 12 for d.
C = 12π
And now we have found the circumference of the circle.
The equation for the area of a circle is:
A = πr²
Where A is the area and r is the radius. Remember that the diameter is double the radius, so we can find the radius:
12 = 2r
r = 6
Now that we know r, we can find the area of the circle:
A = π(6)²
A = 36π
Now we have found the area.
So the circumference is 12π and the area is 36π.
I hope you find my answer and explanation to be helpful. Happy studying.
