Question

Answer all these guestions corectly and i will be so thankfull and will mark u brainiest.

Answer 1

Answer:

1) A = π r² = 22/7 x 10² = 314.28 in²

2)A = π r² = 22/7 x 9² = 254.57 mm²

3) radius = 1/2 diameter

r = 1/2 x 3 = 1.5 in

A = π r² = 22/7 x 1.5² = 7.07 in²

4)A = π r² = 22/7 x 14² =616 cm²

5) radius = 1/2 diameter

r = 1/2 x 1.5 = 0.75 ft

A = π r² = 22/7 x 0.75² = 1.76 ft²

Step-by-step explanation:

You cant mark anyone brainliest if you dont have 2 answers. so I am just copying and pasting so you can mark him brainliest and i dont have to give the wrong answer. lol

Answer 2

1) A = π r² = 22/7 x 10² = 314.28 in²

2)A = π r² = 22/7 x 9² = 254.57 mm²

3) radius = 1/2 diameter
r = 1/2 x 3 = 1.5 in

A = π r² = 22/7 x 1.5² = 7.07 in²


4)A = π r² = 22/7 x 14² =616 cm²


5) radius = 1/2 diameter
r = 1/2 x 1.5 = 0.75 ft

A = π r² = 22/7 x 0.75² = 1.76 ft²
