Question

Determine the value of 'R' and 'D' using the information given in the table below.

• A. R = 23
  D = 7
• B. R = 32
  D = 24
• C. R = 6
  D = 32
• D. R = 24
  D = 6

Answer 1

The correct option is B R = 32

D = 24
As we know,
Diameter = 2 × Radius

Radius = $\frac{Diameter}{2}$

Let's use these formulae to determine the value of 'R' and 'D'.

In case of Circle 1,
Diameter = 64 m
Radius $=$ $\frac{Diameter}{2}$
$=\frac{64}{2}m$
$=32m$
Hence, R = 32 m

In case of Circle 2,
Radius = 12 m
Diameter = 2 × Radius
= 2 × 12 m
= 24 m
Hence, D = 24 m
