Answer : B
Explanation
Step 1:
Given radius r = 3.6 in
Step 2:
Circumference of the Cookie = 2πr = 2(3.14)3.6 = 22.61 in
Answer : D
Explanation
Step 1:
Given diameter = 4.8 m ; radius r = 4.8/2 = 2.4 m
Step 2:
Area covered by table = πr2 = (3.14)(2.4)(2.4) = 18.09 square meters
Answer : A
Explanation
Step 1:
Given diameter = 8.4 cm ; radius r = 8.4/2 = 4.2 cm
Step 2:
Area of Circle = πr2 = (3.14)(4.2)(4.2) = 55.39 square cm
Answer : C
Explanation
Step 1:
Given radius r = 10.2 cm
Step 2:
Circumference of Photo frame = 2πr = 2(3.14)10.2 = 64.06 cm
Answer : C
Explanation
Step 1:
Given radius r = 2.8 m
Step 2:
Area of Table = πr2 = (3.14)(2.8)(2.8) = 24.62 square meters
Answer : A
Explanation
Step 1:
Given radius r = 7.2 cm
Step 2:
Circumference of Bowl = 2πr = 2(3.14)7.2 = 45.22 units
Answer : B
Explanation
Step 1:
Area of Circle = πr2 = (3.14) r2 = 47.76 square meters
Step 2:
r2 = 47.76/3.14 = 15.21; Taking square roots Radius r = 3.9 m
Answer : D
Explanation
Step 1:
Given radius r = 6.4 in
Step 2:
Area of Cheese layer = πr
Step 3:
Answer : A
Explanation
Step 1:
Given diameter = 210 ft ; radius r = 210/2 = 105 ft
Step 2:
Circumference of Ferris Wheel = 2πr = 2(3.14)105 = 659.4 ft
Answer : C
Explanation
Step 1:
Circumference of Circle = 2πr = 2(3.14)r = 16.52 ft
Step 2:
Radius r = 16.52/(2 × 3.14) = 2.63 ft
