Question:

A new park was designed to contain two circular gardens. Garden A has a diameter of 50m and garden B has diameter of 70m if the gardener wants to outline the gardens edging, how many meters will be needed to outline the smaller garden?

Answers

  157

Step-by-step explanation:

The circumference of a circle with diameter d is given by ...

  C = πd

The circumference of a 50 meter circle will be ...

  C = π(50 m) ≈ 157.08 m

It will take about 157 meters of edging to outline the smaller garden.

5809m²

Step-by-step 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

50 x 3.14 = 157m.    A

70 x 3.14 = 220m.    B

220 + 157 = 377m of fabric

Step-by-step explanation:

[tex]5,811.95\ m^2[/tex] of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the  area of the two gardens.

-We calculate the combined areas as:

[tex]A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2[/tex]

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.

about 78.539 meters. smallest diameter = 50. plug that into the equation C = πd
