201.06 square units The formula for calculating the surface area (A) of a sphere is. ##color(red)(|bar(ul(color(white)(a/a)color(black)(A=4pir^2)color(white)(a/a)|))## where r is the radius. Given the circumference we can […]

Given that Point T##(3 8)## is reflected across the ##x##-axis. Point T’ is its reflection as shown in the figure. It is cleat that T’ is […]

##arcsin(sqrt(3)/2)=60=pi/3## ##sqrt(3)/2## is a known value and the main angle ##alpha## that has ##sin(alpha)=sqrt(3)/2## is ##alpha=60=pi/3##. Because arcsin is a function ##RR->[-1;1]## we take only the […]

Perimeter is ##38## ##cm.## Perimeter of a rectangle with length ##l## and width ##w## is given by ##2xx(l+w)## Hence perimeter of a rectangle with length ##15## […]

A quadrilateral is any polygon with ##4## sides. There are many different types of .

See explanation. The converse of the Isosceles Triangle Theorem states that if two angles ##hat A## and ##hat B## of a triangle ##ABC## are congruent then […]
