irinina [24]

Answer:

24 stickers of people

Step-by-step explanation:

you have 48 stickers in total, therefore make the denominator equal 48 by muliplying each fraction by 6/6

3/8 x 6/6 = 18/48

1/8 x 6/6 = 6/48

add those together to get the total stickers without people

18/48 + 6/48 = 24/48

this means half don't have people

then you can subract that number from the total and you will find the stickers with pictures of people

48/48 - 24/48

24/48

Find the surface area, to the nearest square centimeter, of a cylinder with diameter 6 cm and height 8 cm. A.48cm^2 B.452cm^2 C.
Black_prince [1.1K]

The right answer is Option C.

Step-by-step explanation:

Given,

Diameter = 6 cm

Radius = \frac{Diameter}{2}=\frac{6}{2}=3\ cm

Height = 8 cm

π = \frac{22}{7}

Surface area = 2πrh+2πr²

Surface area = 2*\frac{22}{7}*3*8+2*\frac{22}{7}*(3)^2\\

Surface area = \frac{1056}{7}+\frac{396}{7}=\frac{1056+396}{7}

Surface area = \frac{1452}{7}

Surface area = 207.4 cm²

Rounding off to nearest whole number

Surface area = 207 cm²

The surface area of cylinder is 207cm².

The right answer is Option C.
