What is the radius of a sphere whose surface area is 100 square centimeters?

Mathematics
1 answer:
professor190 [17]3 years ago
7 0

Answer:

Step-by-step explanation:

The formula for determining the surface area of a sphere is expressed as

Surface area = 4πr^2

Where

r represents the radius of the sphere

π is a constant whose value is 3.14

From the information given,

Surface area of the sphere = 100 centimeters ^2. Therefore,

100 = 4 × 3.14 × r^2

100 = 12.65r^2

r^2 = 100/12.65 = 7.9051

r = √7.9051

r = 2.81 centimeters

= 32 / 100

= 32%

Serga [27]
If its meaning making a profit after the $300 then:
540+300=840
840/24= 33.60
They would charge $33.60 per necklace.

If you were meaning a profit of $540 total then:
540/24=22.5
They would charge $22.50 per necklace.
