Answer:
622.13 square units
Step-by-step explanation:
Area of the composite figure = area of parallelogram + area of circle
Note: 2 semicircles = 1 full circle
Area of the figure = a*h + πr²
Where,
a = 22
h = 11
r = ½ of 20 = 10
Plug in the value into the equation
Area = 22*11 + π*11²
Area = 242 + π*121
Area = 622.13271108 ≈ 622.13 square units (nearest tenth)
Answer:
500%
Step-by-step explanation:
We find the volume of pyramid A
Pyramid A is a square pyramid with a base side length of 9 inches and a height of 10 inches.
Volume = a² h/3
Where a = 9 in
h = 10 in
Volume = 9² × 10/3
Volume = 270 cubic inches
Pyramid B has a volume of 1,350 cubic inches.
Step 2
We compare both volumes
Pyramid A : Pyramid B
270: 1350
= 270/ 1350
= 1 /5
Hence, Pyramid B is 5 times bigthan ger pyramid A
In percent, it is the volume of Pyramid B 500% bigger than Pyramid A
After 2 years-$4608
After 4 years-$4246.73
After 7 years-$3757.24
Answer: C
Step-by-step explanation:
Yes, because the population values appear to be normally distributed
=> 4(7)–2(7+a)=8
<h3>=>28–14
<em>–</em>2a=8</h3><h3>=>14–2a=8</h3><h3>=>-2a=8–14</h3><h3>=>
<em>-</em>2a=-6</h3><h3>
<em>=>a=3</em></h3>
