A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh
1 answer:
The radius of the given circle with a central angle of 7π/10 and arc length of 33cm is 15cm.
It is given that
The central angle of the given circle = 7π/10 radians
Length of arc = 33cm
<h3>What is the formula for arc length?</h3>Arc length = central angle* radius
From the above formula
Radius = Arc length/Central Angle
Radius =
Radius = 15cm
Therefore, radius of the given circle is 15cm.

The simplest form of an interest equation is A = P(1+rt)
where A = the total amount of money at the end, P = the principal (or amount of money you started with), r = the rate in percent, and t = the time in years.
In this case, P = 15000, r = 0.03 (because 3% in decimal form is 0.03), and t = 1:
So, after 1 year he will get $15450 back, making him $450 more.
