Answer:
Step-by-step explanation:
1) 15% of 75 = (15/100) * 75 = 0.15*75 = 11.25
2) 7% of 980 = 0.07 * 980 = 68.6
3) 45%of 62 = 0.45 * 62 = 27.9
4) 22% of 198 = 0.22 * 198 = 43.56

Answer:
The diameter of the circle is 19 m
Step-by-step explanation:
The formula of the area of a circle is A = π r², where r is its radius
<em>To find the diameter from the area of the circle equate the formula of the area by the value of the area to find r, then multiply r by 2 because the diameter of a circle is equal twice its radius</em>
<em />
∵ The area of the circle is 90.25 π m²
∵ A = π r²
- Equate A by 90.25 π
∴ π r² = 90.25 π
- Divide both sides by π
∴ r² = 90.25
- Take √ for both sides
∴ r = 9.5
∵ The diameter of a circle is twice its radius
∴ d = 2 r
- Substitute r by 9.5
∴ d = 2(9.5)
∴ d = 19
The diameter of the circle is 19 m
