Answer 2

49 - 9π

Explanation:

Area of white portion = area of triangle - area of circle

To find the area of the triangle:

The area of a triangle can be calculated using this formula

`A=(bh)/(2)` where b = base length and h = height

The height given is 7m and the base length given is 14m

That being said we plug in the given values into the formula

`(14*7)/(2) \\14*7=98\\(98)/(2) =49`

Hence, the area of the triangle is 49 sq meters.

To find the area of circle

( note that the area is in terms of pi; shown by the answer choices. )

Formula for area of a circle =
`A=\pi r^2`

We are given the diameter ( 6m )

However, we need the radius

To convert diameter to radius we divide by 2

6/2 = 3 so the radius = 3m

Now we plug in 3 into the formula

`A=\pi 3^2\\3^2=9\\A=9\pi`

Remember we do not apply pi because the answer should be in terms of pi.

Now we subtract the two

Area of white portion = 49 - 9π

Hence, the answer is A
