There are 2 circular bases: A = π r²
A = π (3)²
   = 9 π

There is one lateral face that is a rectangle: A = L x W
In this instance, the length equals the perimeter of the circle: L = 2 π r
A = 2 π (3) x 7
   = 42 π

Surface Area = 2(9 π) + 42 π
                       = 18 π + 42 π
                       = 60 π
                       ≈ 188

2 π x 3 x 7 + π x 3^2 x2= 60 π= 188

Find the possibility of rolling even numbers three times, using a six-side die number from 1 to 6

seraphim [82]

Answer:

$\frac{1}{8}$

Step-by-step explanation:

Number of sides of die = 6

Number of sides with even numbers = 3

P( rolling an even number 1 time) = $\frac{3}{6}$ = $\frac{1}{2}$

P(rolling even number 3 times) = $\frac{1}{2}$ x $\frac{1}{2}$ x $\frac{1}{2}$ = $\frac{1}{8}$

Write the product in simplest form: 3w^4 * (-5w^2)

Grace [21]

$3w^{4} (-5w^{2} ) = -15w^{6}$

I think this is what you want? When multiplying with exponents, you either add or multiply the exponents.

When you multiply the exponent:

(x²)³ = $x^{6}$

$(3x^{4} )^{2}$ = 9 $x^{8}$

When you add the exponents:

(x²)(x³) = $x^{5}$

(x²)(x²) = $x^{4}$

$(x^{4} )(x^{3} ) = x^{7}$
