 According to formulas, the measurement of arc DF is twice the measurement of ∡DEF. Arc DF is equal to 360-248 or 112. Hence ∡DEF is equal to 56 degrees.<span>

Alecsey [184]

Answer:

C. 15 cm

Explanation:

The radius is the same in a circle. PA and PB has same length of 8 cm.

In order to find AC, find the length of PA and PC.

Here given:

  • PA = 8 cm
  • PC = PB + BC = 8 cm + 9 cm = 17 cm

Hence solve using Pythagoras theorem:

  • a² + b² = c²
  • AC² + PA² = PC²
  • AC² + 8² = 17²
  • AC² = 289 - 64
  • AC = √225
  • AC = 15

question 12(multiple choice worth 1 points) (03.05 lc) what is the volume of a sphere with a radius of 6 inches? 112π cubic inch
Sladkaya [172]

 volume of a sphere with a radius of 6 inches is 288π cubic inches.

<h3>What is volume of a sphere?</h3>

A sphere is a collection of points in space that are separated from the center by an amount r. The volume of a solid in three dimensions is the area it occupies. The cubic is the unit of volume ( in3,ft3,cm3,m3 , etc ). Ensure that all measurements are made in the same unit before estimating the volume. A sphere's volume, V, is equal to four thirds of pi times the square of the radius.

V=43πr3

Half of the connected sphere's volume makes up a hemisphere. A sphere's volume is 2/3 that of a cylinder with the same radius and height that is equal to its diameter.
