Question

A new park was designed to contain two circular gardens. Garden A has a diameter of 50 m, and garden B has a diameter of 70 m. The gardener wishes to put down weed block fabric on the two gardens before the plants are planted in the ground. How much fabric will be needed to cover the area of both gardens?

Answer 1

Answer: 5809m²

Explanation:

A=pi x r²

so you do 50 divided by 2 because we have diameter no radius, so we get 25

and we do 70 divided by 2 and get 35

since there is a "²" we will do 35x35 and get 1225

and 25x25 and get 625

and THEN we do 625x3.14(aka pi), the same for 1225, we do 1225x3.14 and we get 1962.5 (for the 625 thing) and 3846.5(1225 thing)

Then we do 1962.5 + 3846.5 because we are finding the area of 2 gardens, so we get 5809m²

Answer 2

50 x 3.14 = 157m. A

70 x 3.14 = 220m. B

220 + 157 = 377m of fabric
