Step-by-step explanation:
I will assume that the shaded region is the fire pit
Given


Required
Determine the area of the fire pit
First, calculate the area of the big circle.

Area of the small is:

The area of the pit is:







Answer:
30.5 cm
Step-by-step explanation:
0 < h ≤ 10 ⇔ Midpoint = 5
10 < h ≤ 20 ⇔ Midpoint = 15
20 < h ≤ 30 ⇔ Midpoint = 25
30 < h ≤ 40 ⇔ Midpoint = 35
40 < h ≤ 50 ⇔ Midpoint = 45
50 < h ≤ 60 ⇔ Midpoint = 55
<u>⇒ </u><u><em>Multiply each corresponding midpoint with it's frequency</em></u>
(5 × 1) + (15 × 4) + (25 × 7) + (35 × 2) + (45 × 3) + (55 × 3) = 610
<u>⇒ </u><u><em>Divide the total of 610 by the frequencies added together</em></u>
610 ÷ (1 + 4 + 7 + 2 + 3 + 3) = 610 ÷ 20 = 30.5

Answer:
Area of Tamara room
=9556 square feet
Width
=813 feet
Length= 11.75 feet
Total area= 19794 square feet
480 square feet will not be enough
Step-by-step explanation:
Dimensions of Tamara's room to the nearest whole numbers
Area of Tamara room
=9556 square feet
Width
=813 feet
For the length
Length*width= area
Length= area/width
Length= 9556/813
Length= 11.75
To the nearest whole number = 12 feet
The ceiling is 12 feet high
Let's calculate for the area of the combination
1)Height and width two times
2)Height and length two times
1).area = 12*813
= 9756
Then 9756*2= 19512
2). area= 12*11.75
= 141
Then 141*2= 282
Total area = 282+19512
Total area= 19794
