Answer:828.96m^2

Step-by-step explanation:

radius(r)=8m

L=25m

π=3.14

total surface area of cone(tsa)=πxr^2+πxrxL

Tsa=3.14x8^2+3.14x8x25

Tsa=3.14x8x8+3.14x8x25

Tsa=200.96 + 628

Tsa=828.96

P( x) =x^3-6x^2-5x-14 What is the remainder R when the polynomial p(x) is divided by (x-7)
Igoryamba

Answer:

The remainder is zero

Step-by-step explanation:

To find the remainder we will use the long division

\frac{x^{3}-6x^{2}-5x-14}{x-7}=x^{2}\frac{x^{2}-5x-14 }{x-7}⇒(1)

\frac{x^{2}-5x-14}{x-7}=x\frac{2x-14}{x-7}⇒(2)

\frac{2x-14}{x-7}=2⇒(3)

From (1) , (2) and (3)

The quotient of the long division is x^{2}+x+2 and no remainder

So the remainder is zero

* If you want to check your answer Multiply the quotient by the divisor

(x^{2}+x+2)(x-7)=x^{3}-6x^{2}-5x-14

Not sure how there can be two possible answers unless you're mentioning the decimal form:
