Answer/Step-by-step explanation:

Square = 4 equal sides

1 side = 10 cm

So,

A+B+D+C = 10+10+10+10

so it equals 40

But we arfe looking for half of it or adding of the sides,

B+D

10 + 10 = 20

<h2><u>Answer = 20 cm </u></h2>

You could have also done it by :

The whole thing is 40, and a square has 4 sides. We are looking at 2 sides which is half so ,

40/2 = 20 cm

<h2><u>Answer: 20 cm</u></h2>

Answer:

The area of the face is 15 cm^2

Step-by-step explanation:

The formula for volume is

V = Bh where B is the area of the base and h is the height

90 = B * 6

Divide each side by 6

90/6 = 6B/6

15 = B

The area of the face is 15 cm^2

(b) The globe has a radius of 28.5 cm. Find the surface area of the globe. Round your answer to two decimal places. Use:

damaskus [11]

Answer:

$\boxed {\boxed {\sf 10,207.03 \ cm^2}}$

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:

$SA= 4 \pi r^2$

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

r= 28.5 cm

$SA= 4 \pi ( 28.5 \ cm)^2$

Solve the exponent. Multiply the number by itself.

(28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²

$SA= 4 \pi (812.25 \ cm^2)$

Multiply 4, pi and 812.25 centimeters together.

$SA= 12.56637061 (812.25 \ cm^2)$

$SA= 10207.03453 \ cm^2$

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).

$SA \approx 10207.03 \ cm^2$

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