Answer: Area of circular pool is 47.8 ft².
Step-by-step explanation:
Since we have given that
Circumference of the pool = 25 feet
Let the radius of circular pool be 'r'.
As we know the formula for "Circumference of pool":
So, Area of circular pool will be
Hence, Area of circular pool is 47.8 ft².
Definition of tangent of a given angle α :
tan( α ) = measure of the opposite side / measure of the adjacent side.
For the given case,
angle α = 35 °
measure of opposite side = x cm
measure of adjacent side = 12 cm
From definition of tangent,
tan(35 ° ) = x/12
Isolate and solve for x:
x=12 tan(35) = 12 * 0.7002 = 8.4 cm

Answer:
Kenyan French Roast coffee x=6
Sumatran coffee y=14
Step-by-step explanation:
x+y=20 blend coffee
8x+7y=7.3(20) selling price
x+y=20 ⇒ x=20-y
substitute in the equation:
8x+7y=7.3(20)
8(20-y)+7y=7.3(20) for 20 pound blend
160-8y+7y=146
-y=146-160
y=14 pond
x+y=20
x=20-14=6
check : 14*7+6(8)=146/7.3=20 pound
