Answer:
a=1/2
Step-by-step explanation:
first we need to isolate a squared. so we add 1/4 to both sides
then you take the square root of a square to get 1/2
to check, 1/2 * 1/2 = 1/4
1/4-1/4 = 0
Answer:
V= about 4,222.3 units
Step-by-step explanation:
d=24 so r=12 d/2=r
V= pi r sq times h/3
V=pi 12 sq times 28/3
V= pi 144 (28/3)
V= about 4,222.3
Answer:
the area of the circle is 102.11 square metres
Answer:
124 ft2
Step-by-step explanation:
The yard is a 12ft square so the length and width would both be 12ft. You multiply the length and width of the yard to get the area of the yard so 12x12=144. You have the length and width of the flower bed so 5x4=20. Once you have the area of both you can subtract the area the flower bed takes up of the lawn. 144-20=124 ft2.
