What is the surface area of a cone that has a radius of 5 units and a height of 10 units? Use 3.14 for π and round your answer to the nearest whole number. 254 units2 300 units2 314 units2 384 units2

Surface area of a cone = 254 unit² (Approx)

Step-by-step explanation:

Given:

Radius(r)=  5 unit

Height(h) = 10 unit

Find:

Surface area of a cone

Computation:

Surface area of a cone = πr(r + √h²+r²)

Surface area of a cone = (3.14)(5)(5 + √10²+5²)

Surface area of a cone = 15.7(5 + √100+25)

Surface area of a cone = 15.7(5 + √125)

Surface area of a cone = 15.7(5 + 11.18)

Surface area of a cone = 15.7(16.18)

Surface area of a cone = 254.026

Surface area of a cone = 254 unit² (Approx)

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
