A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT
Ganezh [65]

Answer:

The inner surface area of a hemispherical bowl will be: 1923.25 cm²

Step-by-step explanation:

Given

d = 35 cm

as

r=\frac{d}{2}

  =\frac{35}{2}

   = 17.5 cm

The inner surface area of a hemispherical bowl = 2πr²

=2\times 3.14\times \left(17.5\right)^2

=6.28\:\times \:17.5^2

=1923.25

Hence, the inner surface area of a hemispherical bowl will be: 1923.25 cm²

Given: △KLM, LM=20 3
egoroff_w [7]

Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.

KM = 30 + 10√3

KL = 10√6

(sorry i'm not too sure if my "reasons" for statement/reason is correct)
