Please I need your help with maths!! 1. Calculate the area (use π= 3.14)
Circumference =314m

2. Calculate the circumference (π=3.14)
1. 10cm
2. 10.2cm
3. A=314m2

Step-by-step explanation:

Circumference = 314

2*pi*r = 314

2*r = 314 / 3.14

2*r = 100

r = 50

Area = pi * r^2

Area = 3.14 * 50^2

Area = 3.14 * 2500

Area = 7850

C = 2*pi * r

C = 2 * 3.14 * 10

C = 6.28 * 10

C = 62.80 cm

C = 2*3.14*10.2

C = 64.056

Area = pi * r^2

314 = 3.14 * r^2

314 / 3.14 = r^2

100 = r^2

sqrt(100) = sqrt(r^2)

r = 10

C = 2*pi *r

C = 2*3.14 * 10

C = 6.28 * 10

C = 62.8

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
