Answer:
The first 4 are correct and the last one is incorrect
Step-by-step explanation:
1. The diameter of the circle is 30.8 m ( Correct )
Radius = 15.4 so diameter is 2 times the radius which is 30.8 m
2. The circumference in terms of π is 30.8 π ( Correct )
Circumference = π × Diameter
Circumference = π × 30.8
Circumference = 30.8 π
3 . The circumference of the circle can be found using 2 × π × 15 . 4 ( Correct )
Circumference = π × Diameter
Circumference = π × 30.8
Circumference = 30.8 π
4 . The approximate circumference of the circle rounded to the nearest tenth is 96.7 m ( Correct )
Circumference = 30.8 π = 96.7610537306
5 . A little more than 6 diameters could be wrapped around the circle
( False )
Circumference = 96.7610537306
Diameter = 30 . 8
96.7610537306 ÷ 30 . 8 = 3.14
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.
