Answer:

875 ft²

Step-by-step explanation:

Given 2 similar rectangles with ratio of sides = a : b, then

ratio of areas = a² : b²

Here the ratio of sides = 5 : 25 = 1 : 5, thus

ratio of areas = 1² : 5² = 1 : 25

Thus the area of EFGH is 25 times the area of ABCD

area of EFGH = 35 × 25 = 875 ft²

Ms.Friedman and Mrs.Elliot both teach sixth grade math. They share a storage closet. What is the total area of both rooms and th
Citrus2011 [14]
Answer:
Total area of both rooms and the storage = 2844 ft^2

Explanation:
Total area would initially be the summation of the area of Ms. Friedman's room and storage added to Mrs. Elliot's room and storage.
However, we are given that the storage is shared.
So now, the total area would be equal to Ms. Friedman's room and storage + Mrs. Elliot's room and storage - area of closet

Now, we can notice that:
Ms. Friedman's room and storage = Mrs. Elliot's room and storage

Therefore:
Total area = 2*Ms. Friedman's room and storage - area of storage

1- getting area of Ms. Friedman's room and storage:
length = 36 ft 
width = 40 ft
area of Ms. Friedman's room and storage = length * width
area of Ms. Friedman's room and storage = 36 * 40
area of Ms. Friedman's room and storage = 1440 ft^2

2- getting area of closet:
length = 36 - 30 = 6 ft
width = 40 - 34 = 6 ft
area of closet = length * width
area of closet = 6 * 6 = 36 ft^2

3- total area of both rooms and the storage:
Total area = 2*Ms. Friedman's room and storage - area of storage
Total area = 2*1440 - 36 
Total area = 2844 ft^2

Hope this helps :)

The area of a circle is 80 square inches. Find the area of the sector whose central angle is 45 degrees
Pie
The whole circle (in terms of area) is 360 degrees. 
Area of Sector = (angle / 360) * Area of the entire circle
Area of Sector = (45 / 360) * 80 in^2
Area of sector = (1/8) * 80 in^2
Area of sector = 10 in^2

Answer:

3,813.33 \:  {cm}^{3}

Step-by-step explanation:

Volume of the space that is not occupied = Volume of cube shaped box - volume of soccer ball

=  {20}^{3}  -  \frac{4}{3}  \times 3.14 \times  {10}^{3}  \\  \\  = 8000 -  \frac{4}{3}  \times 3.14 \times  1000 \\  \\   = 8000 -  \frac{4}{3}  \times 3140 \\  \\  = 8000 -  \frac{12560}{3}  \\  \\  = 8000 - 4,186.66667 \\  \\  = 3,813.33333 \\  \\  = 3,813.33 \:  {cm}^{3}
