(-3√7)^2= 9*7=63  when you raise to the second power, -3 becomes 9
and √7 becomes 7
(3√11)^2=9*11=99
99+63=162

(-3\sqrt{7})^{2} + (3\sqrt{11})^{2} \\(-3\sqrt{7})(-3\sqrt{7}) + (3\sqrt{11})(3\sqrt{11}) \\9\sqrt{49} + 9\sqrt{121} \\9(7) + 9(11) \\63 + 99 \\162

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone i
Dovator [93]

we can use

volume of cone formula

V=\frac{1}{3} \pi r'^2 h'

where

r' is radius of cone

h' is height of cone

we are given

The radius of the cone is half the radius of the cylinder

so,

r'=\frac{r}{2}

The height of the cone is equal to the radius of the cylinder

so,

h'=r

now, we can plug values into formula

we get

V=\frac{1}{3} \pi (\frac{r}{2})^2*r

we can simplify it

V=\frac{1}{12} \pi r^3

so, option-C.........Answer

Ann [662]

Given:

The given statement are:

a. Eight less than the product of seven and x.

b. The sum of six and the product of three and d.

To find:

The expression for the given statements.

Solution:

a.

Product of 7 and x is 7×x = 7x.

Eight less than the product of seven and x is 7x - 8.

Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.

b.

Product of 3 and d is 3×d = 3d.

The sum of six and the product of three and d is 6+3d.

Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.
