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
Answer:
y= 1/2x-1
Step-by-step explanation:
The equation of a line is y= mx+c
m represents the slope of the line
c represents the y-intercept
So we plug in our information into the equation.
The slope is 1/2 so y= 1/2x + c
The line crosses at (0,-1) which makes -1 the y-intercept as the line crosses at this point on the y-axis.
Therefore, y= 1/2x-1
32m = 8m · 4
56mp = 8m · 7p
32m + 56mp = 8m(4 + 7p)
The volume of the triangluar block is 4 cubic inches. What is the approximate length of y? -- 2.8 inches
If A,B and C lie on the same line:
4x- 9 + 3x+5 = 17
7x = 21
x = 3
