Calculate 90÷360× pie x 3² in terms of pie.

Answer 1

First, calculate the division and multiplication:

90 ÷ 360 = 0.25
0.25 x π x 3² = 0.25 x π x 9
= 2.25π

Therefore, 90÷360×π×3² in terms of π is equal to 2.25π.

Answer 2

Add the answer with 30cm²

Answer 3

Adding the area of 2.25π with 30cm²:

2.25π + 30cm² ≈ 37.07 cm² (rounded to two decimal places)

Therefore, the sum of 2.25π and 30 cm² is approximately 37.07 cm².

Answer 4

The answer must be in terms of pie

Answer 5

2.25π + 30 cm² in terms of π is 2.25π + 30π = 32.25π

Therefore, the sum of 2.25π and 30 cm² in terms of π is equal to 32.25π.
