Answer:

288 cubic cm

Step-by-step explanation:

Volume of the pyramid = 1/3 * base area * height

Base area = 12 * 12

Base area - 144 sq. cm

Height = 6cm

Volume of the pyramid = 144 * 6/3

Volume of the pyramid = 144 * 2

Volume of the pyramid = 288 cubic cm

Cos(30)=x/20(squarerootof)3 (lolz, sorry bout that xd)
x= 30
sin(30)=y/20(squarerootof)3
y=17.32
you'll have to change Y into a fraction or square root I think...
but yee

Screenshot with answers included A circle has a radius of 1 cm.

lora16 [44]

Area = $\pi r^{2}$
area = $\pi$ x 1 x 1 = $\pi$

Circumference = $2\pi r$
Circumference = 2 x $\pi$ x1
Circumference = 2 $\pi$

The circumference is greater than the area

The circumference of the inner circle is 66 ft. The distance between the inner circle and the outer circle is 44 ft. By how many

Ray Of Light [21]

Answer:

276 4/7 ft

Step-by-step explanation:

Let r1 represent the radius of the inner circle. Then its circumference in feet is ...

C = 2πr

66 = 2π(r1)

If the radius of the outer circle is (r1 +44), then its circumference is ...

C = 2π(r1 +44) = 2π(r1) +2π(44)

C = 66 +88π

Then the difference in the circumferences is ...

(66 +88π) - (66) = 88π

Using the given value of π, the difference in circumferences is ...

(88 ft)(22/7) = 1936/7 ft = 276 4/7 ft
