Laci is filling a circular kiddie play pit with balls. The play pit has a radius of 7ft and each bag of balls covers 15 square feet. How many bags would she need to buy to have enough to cover the play pit

10.26 bags

Step-by-step explanation:

Area of circle :

A = πr²

radius, r = 7ft

A = π * 7²

A = π * 49

A = 153.93804 ft²

Since a bag covers 15 ft² ;

Number of bags needed will be :

Area / number of square feet per bag

153.93804 ft² / 15 ft²

= 10.262536 bags

= 10.26 bags

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

a) 7x=7
