A cylinder has a radius of 12m and a height of 30m. Find the surface area and volume
Anastasy [175]

Answer:

Surface Area: 1008π OR 3166.73

Volume: 4320π OR 13,571.68

Step-by-step explanation:

Surface Area Equation:

2πrh+2πr^2

Work:

2π (12) (30) + 2π12^2

2π(360) + 2π(144)

720π + 288π

1008π OR 3166.73

Volume Equation:

πr^2h

Work:

π12^2 (30)

π144 (30)

4320π OR 13,571.68

6. Find QR, if area and altitude PS of ∆PQR are given<br> ar(∆PQR) = 180 cm2, PS = 15​
Slav-nsk [51]

Given:

Area and altitude PS of ∆PQR are ar(∆PQR) = 180cm² and PS = 15​.

To find:

The measure of side QR.

Solution:

According to the given information, PS is an altitude of ∆PQR. It means QR is the base of ∆PQR.

We know that, the area of a triangle is

Area=\dfrac{1}{2}\times Base\times Height

ar(\Delta PQR)=\dfrac{1}{2}\times QR\times PS

Substituting the given values, we get

180=\dfrac{1}{2}\times QR\times 15

180\times 2=QR\times 15

360=QR\times 15

Divide both sides by 15.

\dfrac{360}{15}=QR

24=QR

Therefore, the measure of side QR is 24 cm.
