Find the circumference and area of each. round to nearest tenth: 1) a circle has a radius of 8ft 2) a circle has a diameter of 11cm

№1. Given: r=8 ft, π≈3.14

C=2×π×r=2×3.14×8=50.24=50.2 ft

A=π×r²=3.14×64=200.96=201 ft²

50.2 ft; 201 ft²

№2. Given: D=11 cm, π≈3.14

d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm

C=2×π×r=πD=3.14×11=34.54=34.5 cm

A=π×r²=3.14×(5.5)²=94.985=95 cm²

34.5 cm; 95 cm²

it would be:

c.parallelogram.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
