Answer:
The area of the sector is 25.1327 cm²
Step-by-step explanation:
The area of a sector of circunference delimited by an angle in radians can be calculated by using the formula below:
area = (angle*r²)/2
area = [(4*pi/9)*(6)²]/2
area = [(4*pi/9)*36]/2
area = (144*pi/9)/2
area = 144*pi/18
area = 8*pi
area = 25.1327 cm²
The area of the sector is 25.1327 cm²
The GCF of this would be...
27x + 9y
9 ( 3x + y)
To check... Multiple the back
9 ( 3x + y)
27x + 9y
Answer: 2 enlargments
Step-by-step explanation:
Use proportion for each enlargment you do
Side a=6cm Side b=4cm
6:4=x:7 4:4=b1:7
7*6=4a1 b1=28/4
a1=42/4 b1=7 after first enlrge
a1=10.5 after first enlarge 7:4=b2:7
10.5:4=a2:7 b2=49/4
a2=73.5/4 xb2=12.5 after 2nd enlarge
a2=18.375 after 2nd enlarge
12.5:4=b3:7
18,375:4=a3:7 b3=21.875 cm after 3rd enlargement
a3=32.15after 3rd enlargement
Values after 3rd enlargement are higher than dimension given for picture wall
30 cm by 20 cm
Answer:
<em>22 units</em>
Step-by-step explanation:
Graphed to solve.
Width:
The distance between points K and G, and points J and H is both 4 units. So for both distances between the set of points will be 8 units total.
Length:
The distance between points G and H, and points J and K is both 7 units. So for both distances between the sets of points will be 14 units total.
14 + 8 = 22
