To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr. We need to solve for r.
23 = 2πr
r=3.66
The calculation for surface area is <span>A = 4πr^2.
</span>A = 4<span>π(3.66)^2
Solve for A.
A= 168 cm^2.</span>
Answer:
x = - 6
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis with equation
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, - 7 ) with x- coordinate - 6 , then
x = - 6 ← equation of line
Answer:
Area is 126.5 inches^2
Step-by-step explanation:
Mathematically, to calculate the area of the trapezoid, we use the following mathematical formula;
A = 1/2(a + b) h
here, a and b represents the two parallel sides which is 9 and 14 inches here and h which is the height is 11
Plugging these values into the equation, we have
A = 1/2(9 + 14)11
= 1/2(23)11 = (23*11)/2 = 126.5 inches^2
8 1/4 -> 1/6 hour
How many pages -> 1 hour?
You can use the cross multiply method
= 49.5 pages
Or you change the hours to minutes.
1/6 hour is 10 min.
[1/6 × 60 = 10 ]
Either way you'll get the same answer.
