The radius of a sphere is 7 cm. What is the sphere's volume? Round to the nearest tenth, and use 3.14

1436.8 cm3

Step-by-step explanation:

4/3  π r^3 ; r = 7 (substitute)

4/3 π (7)^3 (cube)

4/3 π 21 (reorder)

4/3 (21) π (muptiply)

28 π (multiply)

87.96 (round)

88cm^3

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
