Answer:

Maths keeps one mentally active. The total surface of a hemisphere = 3(pi)r^2. So if the radius = 10 cm, then the TSA = 3(pi)r^2 = 300(pi) = 942.8571429 sq cm.

Step-by-step explanation:

hope this helps you :)

The length of a rectangular park is 20 feet longer than the width of the park. If the lenght of the park is 36 feet, what is the
lara [203]

Below is a labeled rectangle:

length = w + 20

we know length is 36 so we plug that in:

36 = w + 20

We need to isolate w and to do that we must subtract 20 from both sides:

(36 - 20) = w + (20 - 20)

16 = w + 0

w = 16

width is 16 feet

Hope this helped!

somebody help pls Complete the table by filling in the multiplicative inverse of the numbers below 2,1/5,-4,​
Yakvenalex [24]

Answer:

Suppose we have a random number A.

The multiplicative inverse of A is a number X such that:

A*X = 1

When we work with real numbers, X = 1/A

Then:

A*(1/A) = A/A = 1

This means that (1/A) is the multiplicative inverse of A.

Where we need to have A ≠ 0, because we can not divide by 0.

Now we want to find the multiplicative inverse of the numbers:

2: Here the inverse is (1/2) = 0.5

1/5:  Here the inverse is  (1/(1/5)) = (5/1) = 5

-4: Herre the inverse is  (1/(-4)) = -(1/4) = -0.25
