Answer 1

1. 6.3 cm.
2. 15.54 ft.
3. 5 7/22 cm.
4. 1.5√6 m.
5. 5.0625 in.

Explanation:

Formula :

Radius = 1/2 x Diameter

Solving :

Q1

• 1/2 x 12.6
• 6.3 cm.

Q2

• 1/2 x 31.08
• 15.54 ft.

Q3

• 1/2 x 10 7/11
• 1/2 x 117/11
• 117/22
• 5 7/22 cm.

Q4

• 1/2 x √54
• 1/2 x 3√6
• 1.5√6 m.

Q5

• 1/2 x 10.125
• 5.0625 in.

Answer 2

Radius = half the diameter.

We have been given the diameter, and need to find the radius.

Therefore, divide the given values by 2.

1. 12.6 ÷ 2 = 6.3 cm

2. 31.08 ÷ 2 = 15.54 ft

`\sf 3. \quad 10 (7)/(11) / 2=(10* 11+7)/(11)/ 2=(117)/(11)/ 2=(117)/(11) * (1)/(2)=(117)/(22)=5 (7)/(22)\:cm`

`\sf 4. \quad (√(54))/(2)=(√(9 \cdot 6))/(2)=(√(9)√(6))/(2)=(3√(6))/(2)\:m`

5. 10.125 ÷ 2 = 5.0625 in
