Answer:
8 : 6
4 : 3
Step-by-step explanation:
Just simplify the fraction.
8 : 6
4 : 3
So,
To find the expanded form, split the number into each place value.
11,760,825
10,000,000 (ten million) + 1,000,000 (one million) + 700,000 (seven hundred thousand) + 60,000 (sixty thousand) + 800 (eight hundred) + 20 (twenty) + 5 (five)
10,000,000 + 1,000,000 + 700,000 + 60,000 + 800 + 20 + 5
Answer:
- area ≈ 176.7 cm²
- circumference ≈ 47.1 cm
Step-by-step explanation:
The radius is half the diameter, so is ...
r = d/2 = 15 cm/2 = 7.5 cm
The area formula is ...
A = πr²
Filling in the radius, we have ...
A = π·(7.5 cm)² = 56.25π cm² ≈ 176.7 cm² . . . area
__
The circumference formula is ...
C = πd
Filling in the diameter, we have ...
C = π·(15 cm) = 15π cm ≈ 47.1 cm . . . circumference
