Jenny has a lawn in the shape of a circle of radius 10m.
She is going to cover the lawn in fertilizer.
Fertilizer is sold in bags.
Each bag of fertilizer will cover 26m2 of lawn.
10m
Work out an estimate for the number of
bags of fertilizer Jenny needs.
You must show your working.
Area of a Circle = πr2
π = 3.14
π ≈ 3
Estimate of Area = π x 102 = 3 x 100 = 300m2
Estimate for bag = 30m2
300m2 ÷ 20m2 = 10 bags
10 bags
(4)
(b) Is your estimate for part (a) an underestimate or an overestimate?
Give a reason for your answer.
It is an underestimate, I have rounded π down
so the area will be larger.
I have rounded up the quantity of fertilizer in each bag.
