sorry if its wrong im not the best at math.
Answer:
42 pi
Step-by-step explanation:
The area of the base is the area of a circle
A = pi r^2
A = pi (3)^2 = 9pi in^2
The circumference is
C = 2*pi*r
C = 2*pi*3 = 6pi
The lateral surface area is
lsa = C * h = 6pi *4 = 24 pi
SA = 2 bases + lsa
2 * 9pi + 24 pi
18pi+24 pi
42 pi
The diagram is misleading. The black line on the right side is pointing to the wrong vertex of the red triangle. Instead the diagram should look like this (see attached image below). Notice how the black line on the right is pointing at point D which is the result of rotating point A. What's going on is a 90 degree rotation in the clockwise direction. This is using the algebraic rule (x,y) ---> (y,-x). For instance, point A = (-3,1) maps to (1,3). You swap the x and y coordinates and then change the sign of -3 to +3 which is just 3.
Answer:
Let the side of square be a cm and radius of the circle be r cm
Give, r=12 cm
Area of the square =a2cm2
ΔABC is a right angled triangle.
Thus, by Pythagoras theorem, we have
AB2+BC2=AC2
⇒a2+a2=(2r)2
⇒2a2=4r2
⇒a2=2r2
⇒a2=2(12)2
⇒a2=2×144
=288cm2

53 degrees
Because 180 - 90 ( right angle ) - 37 = 53
