Which best describes the error in finding the surface area of the prism?

1 answer:

3 0

To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.

Find the product of the monomial and the polynomial. 4a^2b^3*(9a^4b^2-4a^2+3)

Artemon [7]

Answer:

Step-by-step explanation:

4a² b³ * (9a⁴b² - 4a² + 3) = 4a²b³ * 9a⁴b² - 4a²b³*4a² + 4a²b³*3

= 36a²⁺⁴ b³⁺² -16a²⁺²b³ + 12a²b³

= 36a⁶b⁵ - 16a⁴b³ + 12a²b³

john bought a full basket of mangoes when he got home he realised 12 out of the 20 mangoes he bought are bad what is the probabi

lara31 [8.8K]

12/20 mangoes are bad so 8/20 mangoes are good and to convert to a percentage we make the denominator 100.
To make 20 to 100 we times by 5 so we do the same to the numerator which is 8
So 8x5 = 40%
Give me brainliest answer plz

The diameter of a circle is 14 in. Find its area in terms of <br> π<br> π.

maksim [4K]

Answer:

49π in²

Step-by-step explanation:

Step 1: Find the radius.

To find radius given diameter, just divide the diameter by 2: $\frac{14}{2}$
14/2 = 7, so the radius is 7.

Step 2: Apply area of circle formula.

The formula to find the area of a circle is πr², where r = radius.
Now, plug in the value of r: π(11)².

Step 3: Simplify.

π(11)²
π(121)
121π

Since we're finding the area in terms of pi, we don't have to multiply 121 by pi, so the answer is 49π in².
