Laquida has a circular a garden with a radius of about 2 ft. If she wanted to plant 40 bulb per square foot about how many should she buy? 120, 240, 480, or 300
A = pi * r^2
A = 3.14 * 2^2
A = 12.56 sq. feet
12.56 * 40 = ?
240
To find out how many bulbs Laquida should buy, we first need to calculate the area of the circular garden.
The formula for the area of a circle is: A = πr^2
where A is the area and r is the radius.
Given that the radius is about 2 ft, we can calculate the area as follows:
A = π(2 ft)^2
Now, let's calculate the area:
A = π(4 ft^2)
Approximating the value of π as 3.14, we get:
A ≈ 3.14 × 4 ft^2
A ≈ 12.56 ft^2
Since Laquida wants to plant 40 bulbs per square foot, we can multiply the area of the garden by 40 to find the total number of bulbs she should buy:
Total number of bulbs = 12.56 ft^2 × 40 bulbs/ft^2
Total number of bulbs ≈ 502.4
Since Laquida cannot buy fractional bulbs, she should round up to the nearest whole number. Therefore, she should buy 503 bulbs.
Based on the given options, the closest answer is 480.
