Answer:

SA = 615.4 yd²

Step-by-step explanation:

The surface area (SA) of a sphere is calculated as

SA = 4πr² ← r is the radius

Here diameter = 14, thus r = 14 ÷ 2 = 7, then

SA = 4π × 7² = 4π × 49 = 196π = 196 × 3.14 ≈ 615.4 yd²

Find the values of the missing angles

solmaris [256]

Answer:

Step-by-step explanation:

Angle A is 55 degrees.

A triangle adds up to 180 in degrees so 60 + 55 = 115

180 - 115 = 65 therefore angle C is 65 degrees.

Angle B is equal to angle C so it's also 65 degrees.

Basically:

A - 55

B - 65

C - 65

Alja [10]

The right answer is: Add 1, then divide by 6

Step-by-step explanation:

Given equation is:

$6x-1 = 11$

The solution of equation means that we have to isolate the variable on one side of the equation

So,

We will solve the equation to write the sequence of operations

So,

Adding 1 on both sides

$6x-1+1 = 11+1\\6x = 12$

Dividing both sides by 6

$\frac{6x}{6} = \frac{12}{6}\\x = 2$

We can see that the sequence is: Add 1 then divide by 6

Hence,

The right answer is: Add 1, then divide by 6

The diagonal of a square is 15 inches. find the area of the square

kondor19780726 [428]

Think of the square as a rhombus:
$\frac{15 \times 15}{2} = \frac{225}{2} = 225 \div 2 = 112.5$
so 112.5 square inches

you can ask if it wasn't clear enough, I will explain.

How do you decide whether a number is a solution of an inequality

disa [49]

Answer:

We can solve inequalities to find all values of the variable that make the inequality true. The idea is to get the variable all by itself on one side of the inequality sign so we can easily see the solutions to the inequality.

Hence for any given inequality and for any given number if we put that number in that inequality and see that the given inequality sign holds true than that number will be a solution of the inequality otherwise it is not an solution of the inequality.
