The surface area of a sphere by definition is given by:
A = 4 * π * r ^ 2
Where,
r: radius of the sphere.
Substituting the values we have:
294 = 4 * π * r ^ 2
We cleared the radio:
r ^ 2 = (294) / (4 * π)
Answer:
An equation that I could use to find the dome's radius is:
A. r2 = 294 square feet ÷ 4π
Answer:
Lines are described as connecting curve joining two points.
Step-by-step explanation:
In coordinate geometry, graph theory, we have points which do not occupy any space.
Any two points can be connected by a curve or a straight line. If two points are joined by a straight line, then we have the slope of the line i.e. the tangent of angle of the line with x axis is constant.
Straight lines would be of the form ax+by+c=0
Hence in equation form, lines would have equations in linear form of both x and y.
Lines have constant slope throughout the region.
Lines can be extended from -infinity to +infinity
Any two distinct points can make a line, but 3 points need not lie on the same line.
3 4×3=12 yeah I'm pretty sure this is right
