she uses 43 kilograms of clay in all
Step-by-step explanation:
First, find the area of the reptile room and the aquarium. A=l*w=72*83=5,976
Second, find the area of ONLY the reptile room. A=l*w. l=72-52=20 w=83-32=51
A=20*51=1,020
Third, find the area of the Amphibian room and the aquarium. A=l*w=72*83=5,976
Fourth, subtract the area of the reptile room from the area of the Amphibian room. 5, 976 - 1,020=4,956=Amphibian room area.
Fifth, add the area of the amphibian room to the area of the reptile room and the aquarium.
4,956+5,976=10,932 ft^2 is the total area of both rooms and the aquarium.
(6a+11)=(2a+83)
6a+11=2a+83
-11 -11
6a=2a+72
-2a -2a
4a=72
4/4a=72/4
a=18
The solution is 18
Answer:
6.14
Step-by-step explanation:
Find area of shaded region:
regtangle area - circle area = shaded area
Regtangle area:
3x3=9
Circle area:
Pi (3.14) x radius x radius= 3.14
area all together if shaded region
9-3.14=6.14
