Mathematics
1 answer:
olga nikolaevna [1]3 years ago
3 0

Answer:

Step-by-step explanation:

C=pi*3           Given

Generally C = 2*pi*r so we need to solve for r

3 pi = 2*pi * r   Divide by 2pi

3 pi/2pi = r

r = 1.5

Area = pi r^2

Area = pi * 1.5^2

Area = 2.25 pi

If you need a 1 number answer

Area = 7.065

“Ms. Blanco drove her car at a speed of 80 kilometers per hour for 1 1/2 hours, then at a speed of 100 kilometers per hour for 2
lara31 [8.8K]
I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250

250+120=370!!

answer : 370 kilometers per hour

The diameter of a table tennis ball is 20 millimeters.
KiRa [710]

The surface area of the table tennis ball will be around 1256.64 mm².

<h3>What is the sphere?</h3>

A sphere is a 3D geometrical object which has a radius and becomes a point that revolves around a fixed point called the center.

A sphere has surface area and volume based upon the radius of the sphere.

For example, if you have a sphere of radius r then its surface area will be 4πr² and volume will be (4/3)πr³.

The table tennis ball is the form of a sphere.

Given that,

The diameter of a table tennis ball is 20

Radius(r) = 20/2 = 10 mm

Surface area of an sphere = 4πr²

So,

Area = 4π(10)² = 1256.64 mm².

Hence "The surface area of the table tennis ball will be around 1256.64 mm²".
