Answer:
1. Radius: 3 Diameter: 6 Circumference: 18.85 Area: 28.27
2. R: 6 D: 12 C: 37.7 A: 113.1
3. R: 9 D: 18 C: 56.55 A: 254.47
4. R: 2.4 D: 4.8 C: 15.08 A: 18.1
5. R: 3.5 D: 7 C: 21.99 A: 38.48
6. R: 7 D: 14 C: 43.98 A: 153.94
Step-by-step explanation:
Radius is half of diameter. Diameter is double radius. Circumference is 2 times pie times radius. Area is pie times radius squared.

The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
<h3>What is an Expression ?</h3>
An expression is defined as a mathematical statement consisting of variables , constants and mathematical operators.
The expression given is
28w⁴x²y⁷+12w⁹x⁸
Factors of the given expression will be the common terms in both the terms
w⁴x² is common in the variable term
The HCF of 28 and 12 is 4
4w⁴x² (7y⁷ + 3w⁵x⁶)
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
