Step-by-step explanation:
Known :
r = 2
Asked :
C = ...?
Answer :
C = 2πr
= 2 × 3.14 × 2
= <u>1</u><u>2</u><u>.</u><u>5</u><u>6</u>

Answer:
slope: -2
Step-by-step explanation:
The equation in terms of x, for the total time he takes in hours would be 2.48 = 12/x + 26/10x
<h3>What is speed?</h3>
Speed can be calculated as the ratio of distance traveled to the time taken
Darpan runs a distance of 12 km and then cycles a distance of 26 km.
Total distance = 12 + 26 = 38km
The running speed is x km/h
A = x
The cycling speed is 10 km/h faster than his running speed
B = 10x
He takes a total time of 2 hours and 48 minutes.
So, the total time he takes
Time = Distance x speed
2.48 = 12/x + 26/10x
10x(2.48) = 120 + 26
24.8x = 146
x = 5.8
