A landscape gardener wishes to spread fertiliser on a semicircular garden bed that has a diameter of 4.7 m. How much fertiliser is required if the fertiliser is applied at the rate of 20 g per square metre? Give your answer to the nearest gram.

Step-by-step explanation:

radius of semicircle =4.7/2 m

area of semicircle=1/2 πr²

=1/2 ×π×(4.7)²

≈8.67 m²

fertiliser=8.67×20

=173.4

≈173 gm

i believe the correct answer is b.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
