Answer:

Step-by-step explanation:
Surface area is the total area of the surface of an object. A globe is a sphere and the formula for calculating a sphere's surface area is:

The radius (r) of the globe is 28.5 centimeters. Substitute this value into the formula.

Solve the exponent. Multiply the number by itself.
- (28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²

Multiply 4, pi and 812.25 centimeters together.


Round to two decimal place or the hundredth place. The 4 in the thousandth place to the right (10207.03453) tells us to leave the 3 in the hundredth place (10207.0<u>3</u>453).

The surface area of the globe is approximately <u>10,207.03 centimeters squared.</u>

1. Solve inside bracket first
7x^2+4x-26+7x^2+3x-15
= (14x^2+7x-41) Answer
2. 5x(6x^2+3x+7)-1(6x^2+3x+7)
= 30x^3+15x^2+35x-6x^2-3x-7
= (30x^3+9x^2+32x-7) Answer

The one the points down shows a negative correlation. a positive correlation points up
your answer here is d
First we want to find the cost of 1 pizza using the given info
let p = pizza(s)
if 5p = 60
then p = 12
so 1 pizza is $12
the cost of 9 pizzas is then simply $12 × 9
9 pizzas cost $108
