Question

Use the diagram to find the indicated measure. Use 3.14 for pi and round your answer

to the nearest hundredths, 2 decimal places, if necessary.
Find the radius.
C = 65.98

Answer 1

10.51 units

Explanation:

Circumference of a circle is given by

C=2πr

Where r is radius and C is the circumference.

Substituting 3.14 for π, 65.98 for C then

65.98=2*3.14*r

Making r the subject of the formula then

r=65.98÷(2*3.14)=10.506369426751

Rounding off, r=10.51 units ( nearest hundredths)
