Answer:
804m²
Step-by-step explanation:
Area = pi × r²
3.14 × 16²
803.84 m²
Approximately, 804m²
<span>Two </span>Angles<span> <span>are </span></span>Complementary<span> <span>when they add up to 90 degrees (a Right </span></span>Angle). They
don't have to be next to each other, just so long as the total is 90 degrees.
So (5x + 4) + ( 7x + 2) = 90
12x + 6 = 90
12x = 90 – 6
12x = 84

Answer:
0.97
Step-by-step explanation:
Given that a homeowner has two smoke detector alarms installed, one in the dining room (adjacent to the kitchen) and one in an upstairs bedroom (above the kitchen). If cooking produces smoke in the kitchen, the probability of setting off the dining room alarm (D) is .95. The probability of setting off the bedroom alarm (B) is .40.
Both alarms are independent of each other.
Probability for smoke detection=P(any one alarm rings)
=P(Kitchen alarm sets off)+P(bed room alarm sets off)-P(Both sets off)
Since both are independent
P(Both) = 
Probability for smoke detection
= 0.95+0.40-0.38
=0.97
Step-by-step explanation:
s = rθ
70 in = (60 in) θ
θ = 7/6 radians
θ ≈ 1.167 radians
