TRUE OR FALSE!
π(Pi) is the circumference of a circle with radius 1.
SHOW HOW YOU KNOW!
FALSE.

Identify the base and the height. Then find the area.
5 cm is the height. 15 cm is the base.
A = bh
A = 5 * 15
A = 75 cm2
7 cm is not perpendicular to 15 cm, so this IS NOT the height.

A groundskeeper needs grass seed to cover a circular field, 290 feet in diameter.
A store sells 50-pound bags of grass seed. One pound of grass seed covers about 400 square feet of field.
What is the smallest number of bags the groundskeeper must buy to cover the circular field?
4 bags.

Identify the base and the height. Then find the area. Justify.
The base and height are determined by the perpendicular lines. Perpendicular lines meet at a 90°, the little square where the perpendicular lines meet tells me that these lines meet at 90°.
We are looking at 10m, 4m, and 14m. These are the measurements that correlate with the perpendicular lines.
The base is the length of the triangle, this does NOT include the dotted line that extends from the triangle. This dotted line helps to form the perpendicular lines, which helps to find the height. So, the base is 14m.
The height is 10m.
