Plz help ill mark u brainliest
egoroff_w [7]

Answer:

<em>Part A:  3,</em>

<em>Part B:  - 4</em>

Step-by-step explanation:

<em>~ Part A ~ </em>

The problem would be in terms of such an expression: ( - 6 - ( - 3 )^2 )/ -5

Now knowing the expression, let us simplify in terms of basic algebra:

( -6 - 9 )/ -5 = ( - 15/ - 5 ) = <em>Answer; 3</em>

<em>~ Part B ~ </em>

We know the problem to be p^2/ r, but we must substitute the value of p being -10, and r ⇒ -25: ( - 10 )^2/ -25

Now let us simplify the expressions:

( - 10 )^2/ -25 = 100/ - 25 =<em> Answer; -4</em>

How would I find the surface area of the cone in terms of pi? It has a radius of 7 cm and a slant height of 19 cm.
julsineya [31]
The formula is SA = \pi r^{2} + \pi rl.  r is the radius and l is the slant height.  In your case it would be 49\pi + 133\pi = 172\pi.

suppose a hole of radius 1 is bored through a sphere of radius 2. what is the volume of the resulting shape
geniusboy [140]

Answer:

21.77

Step-by-step explanation:

Applying,

V = (4/3)π(R²-r²)³/²................. Equation 1

Where  V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie

From the question,

Given: R = 2, r = 1

Constant: π = 3.14

Substitute these values into equation 1

V = 4/3(3.14)(2²-1²)³/²

V = (12.56/3)(3)³/²

V = 4.19(5.196)

V = 21.77
