Q 1 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Radius r = 19 ft

Step 2:

So Diameter = 2r = 2(19) = 38 ft

Step 3:

So, Radius = 19 ft, Diameter = 38 ft

Q 2 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Radius r = 36 in

Step 2:

So Diameter = 2r = 2(36) = 72 in

Step 3:

So, Radius = 36 in, Diameter = 72 in

Q 3 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Diameter d = 44 ft

Step 2:

So Radius r = d/2 = 44/2 = 22 ft

Step 3:

So, Radius = 22 ft, Diameter = 44 ft

Q 4 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Radius r = 18 cm

Step 2:

So Diameter = 2r = 2(18) = 36 cm

Step 3:

So, Radius = 18 cm, Diameter = 36 cm

Q 5 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Diameter d = 98 m

Step 2:

So Radius r = d/2 = 98/2 = 49 m

Step 3:

So, Radius = 49 m, Diameter = 98 m

Q 6 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Radius r = 16 mm

Step 2:

So Diameter = 2r = 2(16) = 32 mm

Step 3:

So, Radius = 16 mm, Diameter = 32 mm

Q 7 - Find the radius and diameter of the following circle. ### Explanation

Step 1:

Given Diameter d = 70 in

Step 2:

So Radius r = d/2 = 70/2 = 35 in

Step 3:

So, Radius = 35 in, Diameter = 70 in

Q 8 - Identify the radius, diameter, and chord from given circle. ### Explanation

Step 1:

The chord is Chord QP

Step 2:

The diameter is Diameter MN

Q 9 - Identify the radius, diameter, and chord from given circle. ### Explanation

Step 1:

Step 2:

The diameter is Diameter MN

Q 10 - Identify the radius, diameter, and chord from given circle. Step 1:
