Answer:
751.124
Step-by-step explanation:
area of a cricle is
πr^2
take π to be 22÷7
A= πr^2
A=22÷7*15*15
A=22÷7*225
7 divides 225
= 34.142
22*34.142
A= 751.124
1. Draw a circle
2. Keeping your compasses open the same distance stick the point on the edge of the circle and draw two little arcs that cut the circle.
3. Stick the point in one the arcs and draw another arc further along the circle. Repeat until you have 6 arcs marked.
4. Use a ruler or straight edge to join up the arcs.
N=7 because u subtract 5 from both sides that gives u 1. Then u add 6 and there’s ur answer
