Hello!

The formula for finding area of a circle is: π · r²

Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.

The diameter is 13. 13 ÷ 2 = 6.5

r = 6.5
6.5² = 6.5 × 6.5 = 42.25

π = 3.14

Multiply 3.14 by 42.25 to get the area

3.14 × 42.25 = 132.665

<em>The area of the circle is 132.665 sq. units, which is the last option.</em>

If the measure of arc GH= 90° and the measure of arc EF= 45°, calculate m∠GDH.

user100 [1]

Answer:

∠ GDH = 67.5°

Step-by-step explanation:

The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

∠ GDH = $\frac{1}{2}$ (GH + EF) = $\frac{1}{2}$ (90 + 45)° = 0.5 × 135° = 67.5°

67592 meters in 2 weeks....2 weeks = 14 days....67592 / 14 = 4828...so he ran 4828 meters per day.

4828 + 1607.87 = 6435.87 meters for that day <==
