First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle.
area of the larger sector:(230/360)π*11.1²≈247.17
area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130
(11.1*11.1*sin130)/2≈47.19
the total area is 247.17+47.19≈294.4
Please use your calculator to double check my numbers.
Answer:
The correct answer will be "60 min/hour".
Step-by-step explanation:
At time 2:00 PM
A car reads = 30 mi/h
At time 2:20 PM
A car reads = 50 mi/h
Now,
At time 2:00 PM
t = 0
At time 2:20 PM
t = 
For MVT,
it’s the 3rd one. so.. 5/8
Answer:
Step-by-step explanation:
If diameter is 14 inches radius = d/2 = 14/2 = 7 inches
Circumference = 2 pi R = 2 × 22/7 × 7
= 44 inches
Area = pi R square = 22/7 × (7)^2
=22/7 × 49
= 154 inches
Hope this helps
When the firecracker hits the ground, H(t) = 0.0 = -16t^2 + 90t + 160 Using the quadratic formula,t = (-90 +- sqrt(90^2 - 4(-16)(160))) / 2(-16)t = -1.42 ort = 7.04
The negative time is extraneous. Therefore,t = 7.04 s.
Seven Seconds is your answer!
