Answer:

46CM

Step-by-step explanation:

Perimeter = S + S + S + S + S + S + S +S

Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2

Perimeter = 46 cm

The other 4 measurements:

5 is from the other side labelled 5 this is because they are equal.

8 is from the other side labelled 8 this is because they are equal too!

The twos are from the difference between 9 and 7.

Answer: 15.7 (1 decimal place)

Step-by-step explanation:

The formula for the circumference of a circle is d(diameter) x π(pi).

The diameter of this is 5 so you would do 5xπ=15.7 (1 decimal place)

For the senior pic mr. Williams is using two cylinders to help keep the food cool the inside still there with the radius of 8 in

Rasek [7]

The answer is 1,695.6 in³.

The volume of the empty space is the difference of the bigger cylinder and the smaller cylinder: V = V1 - V2

The volume of the bigger cylinder is:
V1 = π r² h
r = 10 in
h = 15 in
π = 3.14

V1 = 3.14 * 10² * 15 = 4,710 in³

The volume of the smaller cylinder is:
V2 = π r² h
r = 8 in
h = 15 in
π = 3.14

V2 = 3.14 * 8² * 15 = 3,014.4 in³

The volume of the empty space is:
V = V1 - V2 = 4,710 in³ - 3,014.4 in³ = 1,695.6 in³
