Answer:
The diameter of the circle is 19 m
Step-by-step explanation:
The formula of the area of a circle is A = π r², where r is its radius
<em>To find the diameter from the area of the circle equate the formula of the area by the value of the area to find r, then multiply r by 2 because the diameter of a circle is equal twice its radius</em>
<em />
∵ The area of the circle is 90.25 π m²
∵ A = π r²
- Equate A by 90.25 π
∴ π r² = 90.25 π
- Divide both sides by π
∴ r² = 90.25
- Take √ for both sides
∴ r = 9.5
∵ The diameter of a circle is twice its radius
∴ d = 2 r
- Substitute r by 9.5
∴ d = 2(9.5)
∴ d = 19
The diameter of the circle is 19 m
Answer:
7
Step-by-step explanation:
Given:
m∠CXD = 30°
m∠DXE = 30°
To find:
The measure of angle CXE.
Solution:
The measure of angle CXE is sum of the measures of angle CXD and DXE.
⇒ m∠CXE = m∠CXD + m∠DXE
⇒ m∠CXE = 30° + 30°
⇒ m∠CXE = 60°
The measure of angle CXE is 60°.
