Answer: 26.7 is 13% of 89
Answer:
6000π m²/h
Step-by-step explanation:
Area of the circular cloud =πr²----------------------------------------- (1)
Radius as a function of time = R(t)=50+20t------------------------ (2)
dA/dt = (dA/dr) x (dr/dt)-----------------------------------------------------(3)
dA/dr = 2πr
dr/dt = 20
After 5 hours, the radius of the cloud will be :
R(5)=50+20(5)
= 150 meters
Substituting into (3)
dA/dt = 2π(150) x 20
= 6000π m²/h
Answer:
A
Step-by-step explanation:
hopes this helps
Alll angles in a quadrilateral add to 360
so
missing angle=x
108+99+78+x=360
285+x=360
minus 285 from both sides
x=75
missing angle is 75 degrees
Answer:
21 ft^2
Step-by-step explanation:
split area into two parts shown by the red line and add up both areas to find total area.
area = b×h/2
triangle 1 = (5×6)/2
=30/2
=15 ft^2
triangle 2 = (3×4)/2
=12/2
=6 ft^2
total area = 15+6
