A right cone has radius 5 ft and slant height 9 ft. The radius and slant height are both multiplied by 1/2. Which of the followi
Alekssandra [29.7K]

Answer:

101.07ft^2

Step-by-step explanation:

Given data

radius= 5ft

h= 9ft

When the radius and height are both multiplied by 1/2

radius= 5/2ft = 2.5ft

height= 9/2 ft= 4.5ft

The expression for the surface area of the cone is

A=πr(r+√h^2+r^2)

Substiute

A= 3.142*2.5(2.5√4.5^2+2.5^2)

A= 7.855(2.5√20.25+6.25)

A= 7.855(2.5√26.5)

A= 7.855(2.5*5.147)

A=101.07 ft^2

Hence the surface area is 101.07ft^2

Gnoma [55]

Answer:

Volume of block Jennifer bought:

V = side^3 = 12 x 12 x 12 = 1728 (in3)

Volume of sphere Jennifer wanted to make:

V = (4/3) x pi x radius^3 = (4/3) x pi x (4/2)^3 = 33.5 (in3)

a, The number of spheres she can make:

N = 1728/33.5 = 51.58 = ~51

b, The area of remaining clay after she made a sphere:

A = 1728 - 33.5 = 1694.5 (in3)

Hope this helps!
