Base times height equals area see picture
Answer:
648 sq units
Step-by-step explanation:
Area of the base= 12×12= 144 sq. units
Perimeter of the base=4×12= 48
Total surface area= 1/2×48×21 + 144
=648 sq units
Answer:
A perpendicular bisector of a line segment is a line segment perpendicular to and passing through the midpoint of (left figure). The perpendicular bisector of a line segment can be constructed using a compass by drawing circles centered at and with radius and connecting their two intersections.
Answer:
1520.5 yd²
Step-by-step explanation:
Surface area of a sphere = 4πr², where r is the radius
so,
4πr²
= 4×π×11²
= 484π
= 1520.5 yd²
