Answer:
a) 25446.90 ft²
b) 101787.60 ft²
c) 407150.41 ft²
d) 2025πt²
Step-by-step explanation:
Data provided in the question:
Rate of spread radially = 45 feet per day
a) Radius of spread after 2 days
= 45 × 2
= 90 feet
Therefore,
Area affected = πr²
= π(90)²
= 25446.90 ft²
b) Radius of spread after 2 days
= 45 × 4
= 180 feet
Therefore,
Area affected = πr²
= π(180)²
= 101787.60 ft²
c) Radius of spread after 2 days
= 45 × 8
= 360 feet
Therefore,
Area affected = πr²
= π(360)²
= 407150.41 ft²
a) Radius of spread after t days
= 45 × t ft
Therefore,
Area affected = πr²
= π(45t)²
= 2025πt²
answer windex heres the step by step explanation everything =windex Step-by-step explanation:
2. r/5=9/21
r x 21 = 9 x 5
r= 45/21
r= 2.14 ( the answer is B)
3. 4 cups-> 4 dozen
x cups-> 8 dozen
4/x = 4/8
X x 4= 4 x 8
x= 32/4
x= 8 cups
Answer:
The answer is 55.
Step-by-step explanation:
1. angle ADB and BDC = 180.
180-80= 100 (angle BDC is 100)
because a triangle is 180 degrees, you can figure out CBD...
2. BDC + DCB is the same as
100+25=125
3. 180-125=55
