What is the lateral area and the surface area of a right cylinder that is 10 feet high and has a base with a radius of 5 feet?

Answer with Step-by-step explanation:

The lateral area and surface area of cylinder is given by:

Lateral area=2πrh

Surface area=2πrh+2πr²

where r is the radius and h is the height

Here, h=10 feet

and r=5 feet

Lateral area=2×3.14×5×10  (Let π=3.14)

                  =314 square feet

Surface area=2×3.14×5×10+2×3.14×5×5

                    =314+157

                    =471 square feet

Hence, Lateral Area of cone= 314 square feet

and Surface Area of cone= 471 square feet

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
