The length of the curved surface is the circumfrence of a circle with radius r = 10/2 = 5 decimeters.
Length of curved surface = 2π x 5 = 10π ≈ 31.4 decimeters.
Answer:
250%
Step-by-step explanation:
Where: 80 is the old value and 280 is the new value.
Percent change = [(New - Old ) / |Old|] x 100%
Percent change = [(280 - 80) / |80|] x 100 = [(200) / 80] x 100 = 250 % (decrease)
In this case we have a positive change (increase) of 250 percent because the new value is smaller than the old value.
Answer:
Firest y5/ 4x = y5 - 4 /4X -4
x= y
Answer:
(B) Segments MA and MB
Step-by-step explanation:
The tangent to the circle at a point is perpendicular to the radius of the circle drawn to the point of tangency.
Tangent at a point is unique.
Since there can be no two tangents at a point on circle, the options (b) and (c) are ruled out.
Now, if OA is perpendicular to MA, MA is the tangent else if OA is perpendicular to PA, PA is the tangent. Same is the case with point B.
Tangents from the same external point has same length.
MA = MB since they are the radii of the same circle with center M.
Hence, MA and MB meet all the requirements of the tangents.
The time taken by the two men will be equal to 26 hours
<h3>What is speed?</h3>
The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
here two men are walking at different speeds like
v₁=6 miles per hour
v₂=10 miles per hour
The time taken by them to separated by the distance of 100 miles each so that both of them separated by the distance of 200 miles.
t₁= {100}/{6}=16.66 hours
t₂= {100}/{10}=10 hours
total time taken will be
t₁+t₂=16.66+10=26.66 hours
