Question

If the diameter of a circle is 46 centimeters long, how long is the radius of the circle?OA. 184 centimetersOB B. 11.5 centimetersOC. 92 centimetersOD. 23 centimeters

Answer 1

D. 23 cm

Step-by-step explanation

Diameter is a straight line passing from side to side through the centre of the circle and a radius is a straight line from the centre to the circumference of a circle

the relation between the diameter and the radius of a circle is given by:

`radius=(diameter)/(2)`

(or the diameter is twice the radius)

then

a) let

`diameter\text{= 46 cm}`

now, replace

`radius=(46cm)/(2)=23\text{ cm}`

therefore, the answer is

D. 23 cm
